Serverless Stack #help

Hi everyone. So, I have a monorepo project using Lerna and yarn workspaces with typescript. I want to use sst to develop the rest api and any other serverless requirements. I started simple, using

npx create-serverless-stack@latest my-sst-app --language typescript

. And treating this as one of the packages of the monorepo. The problem begins when I try to use other packages from my monorepo to develop something. I have two packages:

rest-api

this is the sst package

@temis/utils

this is another typescript package Inside

rest-api

I do a

yarn add @temis/utils

in order to use this package as a dependency, and develop some logic. So, I run

yarn build

inside

@temis/utils

and builds successfully. Then I run the same in

rest-api

and when its linting the code, this happens:

Copy code

.../dist/validator/index.js
   3:7    error    Unexpected dangling '_' in '__createBinding'                                                                                                                           no-underscore-dangle

   7:31   error    Assignment to function parameter 'k2'
.........
There was a problem linting the source.
There was an error synthesizing your app.

Note that the sst package is trying to lint the compiled code from

@temis/utils

(using the dist folder: dist/validator/index.js). The tsconfig in

@temis/utils

is simple:

Copy code

{
  "compilerOptions": {
    "declarationMap": false,
    "target": "es5",
    "module": "commonjs",
    "strict": true,
    "allowSyntheticDefaultImports": true,
    "esModuleInterop": true,
    "skipLibCheck": true,
    "forceConsistentCasingInFileNames": true,
    "outDir": "./dist",
    "rootDir": "./src"
  }
}

And the tsconfig in the sst package is the default one, I haven't touched it so far:

Copy code

{
  "compilerOptions": {
    "target": "ES2018",
    "module": "commonjs",
    "lib": [
      "es2018",
      "dom"
    ],
    "types": [
      "node"
    ],
    "declaration": true,
    "strict": true,
    "noImplicitAny": true,
    "strictNullChecks": true,
    "noImplicitThis": true,
    "alwaysStrict": true,
    "noUnusedLocals": false,
    "noUnusedParameters": false,
    "noImplicitReturns": true,
    "noFallthroughCasesInSwitch": false,
    "inlineSources": true,
    "experimentalDecorators": true,
    "strictPropertyInitialization": false,
    "sourceMap": true,
    "baseUrl": ".",
    "esModuleInterop": true,
    "skipLibCheck": true
  },
  "include": [
    "lib",
    "src"
  ]
}

So, anyone has faced this problem before? Maybe its related to some typescript specific config that I don't know yet. I fairly new using typescript. Thank you in advance

Hi I'm new to sst and I'm just trying out an example for the first time in conjunction with aws-vault, but getting this error: 25705 PM | CREATE_FAILED | AWS:IAM:Role | FilePublishingRole The security token included in the request is invalid (Service: AmazonIdentityManagement; Status Code: 403; E steps to reproduce: svn checkout https://github.com/serverless-stack/examples/trunk/rest-api cd rest-api npm i aws-vault exec wadminv --debug -- npm run start However both these execute correctly: aws-vault exec wadminv --debug --no-session -- npm run start aws-vault exec wadminv -- aws s3 ls I'd appreciate some guidance on what to investigate or try?

Hi all! Wondering if you have any recommended resources to learn more about integration / E2E testing for serverless apps? Components I'm working with now include: • EventBridge • Lambda • SQS • DLQs • and will also be using DDB in the near future One of the things I'm struggling to understand is how to test failure modes - like concurrency config issues in Lambda, or errors that cause messages to be stored in a first or second DLQ, and then retried, etc. Seems like part of this overlaps with load testing too 😬 I hope that makes sense 🙂 Thank you for your help!

Hi everyone, looking for general help. Is there an equivalent

Hi there, In the Automating deployments part, chapter: Creating a CI/CD pipeline for React . I have created branch, deployed it for preview. All works fine so I merged the branch to deploy it to production. My question is what happens with the app that was deployed from the branch. I would expect it will vanish when the branch is merged to master but can see it is still accessible. Will it vanish after some time? Or I should code/configure something in addition here? Thanks for your answer 🙂

Hey, I was just curious about this and there were no specific answers that I could find so I am asking here, are lambda cold start times something that I should bother about. My API currently is a REST API and I’ve a different lambda function for every resource URL. I am going to move to AWS AppSync later but how big of problem are lambda cold starts and do lambda cpu / memory configuration affect it in any way?

Hi there. I’m using the typescript starter from your repo - https://github.com/AnomalyInnovations/serverless-typescript-starter - and I wondered if anyone could explain why I’m not seeing any linting error’s in VSCode but they do appear when deploying. I’m sure I’ve missed something obvious

Hi there! Firstly I have to say I love SST, debugging lambdas running in the cloud has turned me from "feedback cycles for faas is too slow" to "PUT ALL THINGS ON LAMBDAS!" I have a question about the debugger, it works for me sometimes, but sometimes not, I understand the general idea of how it works with the websocket/remote debug thing, but when it doesn't work I'm a bit stuck... this is how I'm thinking to figure out what's wrong: 1. Run mitmproxy and filter all requests to amazonaws.com 2. Get my machine to trust the mitmproxy certificate 3. Figure out how to disable cert pinning in aws-sdk/aws-cdk etc. that's making requests from vscode out to the magical "debug" websockets api gateway 4. Look at what happens in the happy path 5. Look at what's missing when it breaks So my questions are: • Does this sound like a solid approach? Is there anything else you'd suggest? (I'm not getting the answers I need from logs by setting DEBUG=1) • Is the debugger functionality know to be a bit flakey? (if this is the case I'm happy to contribute PRs)

Is anyone importing ts enums from node_modules? I'm encountering a really weird issue. I can't tell if it's us or esbuild. i expect this import to get compiled away and never show up in the output js.

Copy code

import { LineItemStatus as TLineItemStatus } from "@canopyinc/api-docs/types/ts/EditLineItemInput.type";

but it remains as an unused variable artifact in the lambda file as

Copy code

var import_EditLineItemInput = __toModule(require("@canopyinc/api-docs/types/ts/EditLineItemInput.type"));

I’m trying to use a custom domain with the Api construct, why would I get an error saying “CREATE_FAILED | AWS:CertificateManager:Certificate | ApiCertificatexxxxx No hosted zone found with ID: xxxx (Service: AmazonRoute53; Status Code: 404; Error Code: NoSuchHostedZone; Request ID: 37cb0031-2b4f-40a7-8e00-7d979975ecb4; Proxy: null)“. Also, point to note that the hosted zone id mentioned in the error and my actual hosted zone id are different values.

Hi all 👋 Question about the Share Code Between Services chapter. I'm following this:

In our example, we want to share some common code. We’ll be placing these in a
libs/
directory. Our services need to make calls to various AWS services using the AWS SDK. And we have the common SDK configuration code in the
libs/aws-sdk.js
file.

So in my monorepo, I have:

Copy code

- service1/
- service2/
- libs/
- - - automation-helper

And in

service1

Copy code

import { convertJsonStrToObj, generateResponse, validatePayload } from '../../libs/automation-helper';

But I'm getting this serverless error when running

serverless invoke local

😭 Any ideas? Thanks!

Hey Frank, as a temporary workaround, is it possible to use a different bundler besides esbuild for local dev? Or at least during the live reload rebuild. I'm still running into this weird bug, https://serverless-stack.slack.com/archives/C01JG3B20RY/p1621909026062100

Copied to #seed Morning. Is there a Seed channel? We'd like to conditionally build some constructs differently for PR envs on Seed. How do we detect when CI is running in a PR env, as opposed to one of the explicit stages we've defined?

Hey all! Really enjoying the framework. Looking for some help with a pretty basic implementation. When I run "yarn run build", I'm getting an error at the Building Lambda function step that reads "Cannot find a handler file at src\functions\test.js". I've changed very little about the package that npx installed (typescript, use-yarn). Just added a functions folder inside the src, and changed the name of the default function to test.ts. I thought that I updated everything appropriately, but maybe not! Any ideas in here about where to start with this?
