Morning all. I'm trying to run

npx sst start

which throws the following error

Copy code

Error: Cannot find asset at my-app/node_modules/aws-cdk-lib/lambda-layer-awscli/lib/layer.zip
    at new AssetStaging (my-app/node_modules/aws-cdk-lib/core/lib/asset-staging.ts:166:13)

    at Module._compile (node:internal/modules/cjs/loader:1101:14)

So I've then proceeded to install the missing asset with

npm i @aws-cdk/lambda-layer-awscli

Rerunning

npx sst start

will then advise that I upgrade AWS CDK packages to V2

Copy code

Preparing your SST app
(node:29303) ExperimentalWarning: stream/web is an experimental feature. This feature could change at any time
(Use `node --trace-warnings ...` to show where the warning was created)

Update the following AWS CDK packages to v2:

  - @aws-cdk/lambda-layer-awscli

More details on upgrading to CDK v2: <https://github.com/serverless-stack/serverless-stack/releases/tag/v0.59.0>

AWS CDK packages need to be updated.

Here's my

package.json

Copy code

{
  "name": "my-app",
  "version": "0.1.0",
  "private": true,
  "scripts": {
    "test": "sst test",
    "start": "sst start",
    "build": "sst build",
    "deploy": "sst deploy",
    "remove": "sst remove"
  },
  "eslintConfig": {
    "extends": [
      "serverless-stack"
    ]
  },
  "dependencies": {
    "@aws-cdk/lambda-layer-awscli": "^1.155.0",
    "@aws-sdk/client-dynamodb": "^3.72.0",
    "@aws-sdk/client-lambda": "^3.72.0",
    "@aws-sdk/client-ses": "^3.82.0",
    "@aws-sdk/client-sesv2": "^3.82.0",
    "@aws-sdk/client-sns": "^3.72.0",
    "@aws-sdk/lib-dynamodb": "^3.72.0",
    "@mailchimp/mailchimp_marketing": "^3.0.74",
    "@serverless-stack/cli": "0.69.6",
    "@serverless-stack/resources": "0.69.6",
    "@sls-next/lambda-at-edge": "^3.7.0",
    "aws-cdk-lib": "2.15.0",
    "md5": "^2.3.0"
  }
}

It doesn't appear that

aws-cdk/lambda-layer-awscli

has a V2 package looking at the versions here - https://www.npmjs.com/package/@aws-cdk/lambda-layer-awscli And my versions of SST and CDK are SST: 0.69.6 CDK: 2.15.0 I found a thread with a similar issue though that seemed to be resolved by a new SST upgrade. Thinking that I've likely missed a step with the V2 migration or have mismatching versions of SST somewhere in my settings

Hello everyone. I have been trying to implement Sentry on my project following this guide: https://serverless-stack.com/examples/how-to-use-sentry-to-monitor-your-serverless-app.html. I am trying to implement the wrapper onto my handler.js main function like this:

Copy code

import * as debug from "./debug";
import Sentry from "@sentry/serverless";

const handler = Sentry.AWSLambda.wrapHandler((lambda) => {
  return async function (event, context) {
    let body;
    let statusCode;

    // Start debugger
    debug.init(event);

    try {
      // Run the Lambda
      body = await lambda(event, context);
      statusCode = body.statusCode || 200;
    } catch (e) {
      // Print debug messages
      debug.flush(e);

      body = { error: e.message };
      statusCode = 500;
    }

    // Return HTTP response
    return {
      statusCode,
      body: JSON.stringify(body),
      headers: {
        'Access-Control-Allow-Origin': '*',
        'Access-Control-Allow-Headers': '*',
        // "Access-Control-Allow-Credentials": true,
        // "Access-Control-Allow-Methods": "GET, PUT, POST, DELETE, HEAD, OPTIONS",
      },
    };
  };
})

export default handler

This function is used by other lambda's to handle API calls, and my problem is that currently It's just sending the REQUEST's but it doesn't return any RESPONSE. Maybe it's something minor that I am missing. If you need any more info I would happily supply.

Morning everyone! I've been trying to give list access to a specific bucket to my lambda. So I tried this

Copy code

const uploadPublicBucket = props.uploadPublicBucket;
apiGateway.addRoutes(this, {
      'GET  /users': {
        function: {
          functionName: `fdm-${id}-${scope.stage}-get-users`,
          handler: 'services/field-data-api/handlers/user.get',
          permissions: [
            'cognito-idp:ListUsers',
            'cognito-idp:DescribeUserPool',
            [uploadPublicBucket.bucketArn, 'ListBucket'],
          ],
        },
      },
    });

But I get this error when I run

sst start

Error: The specified permissions are not supported.

I'm pretty sure there's a way that I can give permission to list a specific bucket to a specific lambda function, if anyone has any hint for me I'd appreciated 🙂

Hi Folks. How do I get the resource name (example:Bucket) for reference in the backend? Is there a way to get it by the ID used to create the resource in the stack?

I am probably blind. Looking for docs around

sst.json

with then intent of defining/deploying multiple Apps to different AWS accounts.

Hello, I am trying to implement AppSync with a Cognito UserPool primary authorization mode (no x-api-key which seems to be the default mode) I have found this example from the SST documentation: https://docs.serverless-stack.com/constructs/AppSyncApi#using-cognito-user-pool But not sure what the

userPool

object is and comes from (as a value). When i look into the CDK

IUserPool

interface i am affraid to have to collect and build this massive object! I hope we can do something from the Auth construct return value to build this object. Do you know if it is possible? I didn't find any example of a AppSync + Cognito User Pool Authorization mode example on the web. If we could simply do a

userPool.attachPermissionsForAuthUsers([api]);

like for API Gateways it would be really nice!

Hey everyone! Right now I have most of my lambda defined into

serverless.yml

, trying to move them over sst but I want to do it over time. As of now, I do use a custom domain for my lambdas in the yaml file. Seed is handling everything with the custom domain. I tried to add a custom domain in my sst apiGateway stack, but it tries to create the custom domain, which I don't want. In the AWS console it is possible to add API mapping on an existing domain. And I was wondering if it is possible with the

APIGatewayV1API

object in sst.

Hey everyone I have 2 questions about the

AppSyncApi

1. My company is requiring all resources in a stack to follow a particular structure. I know you added

stackName

to the StackProps to allow for this but it doesn't seem to propagate to the

AppSyncApi

, just wondering if there is a way to do this? 2. Is it possible to create a custom

graphqlUrl

? At the moment, it is readonly with no

set

method Thanks for any help 🙂

Hello, anyone have use casbin in SST? when i import casbin-node, it shows build error

Copy code

Consider changing "parse" to a default import instead:
    node_modules/casbin/lib/esm/persist/helper.js:1:7:
      1 │ import * as parse from 'csv-parse/lib/sync';

Hi! I've seen more questions about puppeteer and layers but none of the answers worked for me, so I'm just going to give it a try here... I'm using

node v14.19.1

with

npm 8.9.0

. Following https://serverless-stack.com/examples/how-to-use-lambda-layers-in-your-serverless-app.html, it throws the error

Copy code

Cannot find module '/home/dev/layer-chrome-aws-lambda/node_modules/puppeteer-core/lib/cjs/puppeteer/common/Browser'.

This is, by the way, after fixing the

Cannot find a handler file for "lambda.handler"

error by moving

backend/functions/lambda.ts

backend/lambda.ts

(I think the tutorial outdated the new directory structure). Removing the

bundle: { externalModules: ["chrome-aws-lambda"] },

line results in another error:

Copy code

ReferenceError: __dirname is not defined in ES module scope This file is being treated as an ES module because it has a '.js' file extension and '/home/dev/layer-chrome-aws-lambda/.sst/artifacts/dev-layer-chrome-aws-lambda-MyStack-Api-Lambda_GET_-/package.json' contains "type": "module". To treat it as a CommonJS script, rename it to use the '.cjs' file extension.

I've tried multiple workarounds (including downgrading node and npm versions but that caused a lot of other issues) but none seem to work. Any thoughts? Below are the dependencies of my `package.json`:

Copy code

{
  "devDependencies": {
    "@serverless-stack/cli": "^1.0.4",
    "@serverless-stack/resources": "^1.0.4",
    "@tsconfig/node14": "^1.0.1",
    "typescript": "^4.6.4"
  },
  "workspaces": [
    "backend"
  ],
  "dependencies": {
    "chrome-aws-lambda": "^10.1.0",
    "puppeteer": "^14.0.0",
    "puppeteer-core": "^14.0.0"
  }
}

Hi, how do I do this in functional stack?:

Copy code

this.addOutputs({
      ApiEndpoint: this.api.customDomainUrl || this.api.url,
    });

Hi, The following used to work in SST v0.x

Copy code

new RDS(this, 'db', {
      rdsServerlessCluster: {
          credentials: Credentials.fromUsername('admin', {
            secretName: `mySecretName`,
          }),
     }
})

With SST v1:

Copy code

new RDS(this, 'db', {
      cdk: {
          cluster: {
              credentials: Credentials.fromUsername('admin', {
                  secretName: `mySecretName`,
              }),
          }
     }
})

throws the following error (Source):

Copy code

`Only credentials managed by SecretManager are supported for the "cdk.cluster.credentials".`

How is this handled differently in SST v1?

Does anyone know how to map an api gateway in a subaccount to an already created custom domain in a parent account? Is that possible? I’m slowly moving services into environment specific accounts, but the domain will still be registered in the parent. And there are api gateways in that parent account already mapped. so i can’t remove it.

Robert Chandler

Has anyone manage to get

ReportBatchItemFailures

to work with SQS and SST? I'm wondering if we're doing something wrong or if the live lambda development isn't handling this property correctly. Going to test now with a deployed lambda to check

Damjan

Is it possible to use normal Api construct and the graphql interface in console ? I see it’s tagged as graphql: true in metadata but I can’t seem to get it to work.

Dennis Dang

05/12/2022, 5:06 AM

When deployed, eventbridge doesn't direct messages to my queue. While locally (with an admin privileged access keys), the whole flow works from bus to queue to lambda. The deployed server that pushes events to the bus uses the same keys as local dev. I've got this setup working a year ago, but can't recall now how to determine if my resources have the correct IAM permissions. Doesn't CDK already handle resource permissions when you set targets?

(SOLVED) hi everyone! how can

sst start

use

python

from local

conda

environment? It keeps referring to global

/usr/local

installation, which does not have custom packages my guess is that

sst start

disregards my terminal environment and just uses an independent process that uses default values and therefore system python setup 🤔

05/12/2022, 2:27 PM

(SOLVED) Anybody know why there’s no

[Solved] Hi everybody! I've just upgraded to v1 and everything is compiling ok. However I'm getting a typescript error on the Api construct using a User Pool Authorizer (called 'userPoolAuthorizer'):

Copy code

TS2322: Type 'Api<{ userPoolAuthorizer: { type: "user_pool"; userPool: { id: string; clientIds: string[]; }; }; }>' is not assignable to type 'Api<Record<string, ApiAuthorizer>>'.

Types of parameters 'routeProps' and 'routeProps' are incompatible.

Nevermind, turns out Api now takes a generic:

Hi. We are using Seed for deployment, and our Next application failed to build, which seems to be due to a postinstall script by

Hey! I'm switching all my stacks to the new functional pattern. Everything works fine but one little thing. Before I used to pass an id to the constructor, this id was used to name the stack in CloudFormation. Now it uses the function name to name the stack. So instead of reusing the old stacks, CloudFormation tries to create new Stack and as you can imagine I do not want to recreate all my cognito userpools, QLDB database, etc etc. Is there a way that I can change the name that the CloudFormation stack will have besides changing the name of the function? As an example, before I was doing this, and the id was used in the name of the CloudFormation

Copy code

const fdmCognito = new CognitoStack(app, 'fdm-cognito');
...
constructor(scope, id, props) {
    super(scope, id, props);

Now I am doing this

export default function CognitoStack(_ctx_: _StackContext_) {...}

And instead of the id, it uses

CognitoStack

in the name of the CloudFormation stack Thank in advance

Non SST related DynamoDB/Lambda Question I have some items in my database that look like this

Copy code

pk: 'some-pk'
sk: 'unique-id'
active: true
name: 'cool name'

pk: 'some-pk'
sk: 'another-unique-id'
active: true
name: 'some other name!'

I have another item that’s essentially a variable grouping of those items

Copy code

pk: 'bundle'
sk: 'unique-bundle-name'
bundle: ['unique-id', 'another-unique-id']

I want to “add” a bundle to a customers orders. like…

Copy code

// pseudocode

for (const bundle in bundles) {
  const item = await dynamoDb.get(bundle) // get the item by sk
  await dynamoDb.put({...item, customerId })  // put that value into dynamo
}

Should I just do that? Another thing I could do is get each item, then transact write the whole batch. I mostly don’t know a good way to do something for a “group” of items. Articles/ideas welcome.
