Any way to fix the issue above without moving to v2 of the CDK stack (got too many dependencies atm)? I am using SST version 0.42.1

My understanding of how API works is

Copy code

this.api = new sst.Api(this, "Api", {
      customDomain: {
         hostedZome: <http://myCoolSite.com|myCoolSite.com>,
         domainName: <http://api.myCoolSite.com|api.myCoolSite.com>,
         domainAlias: <http://www.api.myCoolSite.com|www.api.myCoolSite.com>,      
      }),

Will create an A record in route53 so you can request that api as

<http://api.myCoolSite.com|api.myCoolSite.com>

. then if you wanted to access that in a front end

Copy code

const reactApp = new sst.ReactStaticSite(this, "ReactSite", {
      path: "frontend",
      environment: {
        REACT_APP_API_URL: this.api.url,

My expectation was that

this.api.url

would return

<http://api.myCoolSite.com|api.myCoolSite.com>

. Is that the expected behavior?

Hey hey, I can see that the question has been asked before but not answered, so I will try my luck 🙏 I am trying to get debugging working in VSCode with Python, but it doesn't work with the example on the website. So I am wondering if there is something else I need to do?

Hi guys when I run 'npm start' from this chapter https://serverless-stack.com/chapters/create-a-new-reactjs-app.html I am receiving this error in the terminal:

Does this really mean, “No sst.Buckets
in this app”? cause I’m sure there is a bucket… just that its a

cdk.Bucket

hello wonderful sst community 🙂 I've been looking through github issues and slack threads, so I guess the answer is NO I will try just in case. Our client has a relatively huge IAC in Terraform. We would like to introduce SST to them but in an incremental way. Is there any way to do this?

Hi team. I've lost linting and type checking in Typescript since upgrading SST. I've noticed that it happens starting in version 0.54.0. I also started getting the same issue here after upgrading https://github.com/serverless-stack/serverless-stack/issues/662

@Frank We are moving from serverless framework to serverless-stack. In serverless framework in offline the lambda can be triggered by post requests which are auto generated. How do you trigger a lamda directly when debugging it in serverless-stack?

I keep getting

Copy code

Oops! Something went wrong! :(

ESLint: 8.7.0

ESLint couldn't find the plugin "@typescript-eslint/eslint-plugin".

(The package "@typescript-eslint/eslint-plugin" was not found when loaded as a Node module from the directory "/Users/daniel/Github/arify-serverless".)

It's likely that the plugin isn't installed correctly. Try reinstalling by running the following:

    npm install @typescript-eslint/eslint-plugin@latest --save-dev

The plugin "@typescript-eslint/eslint-plugin" was referenced from the config file in ".eslintrc.json » eslint-config-serverless-stack".

If you still can't figure out the problem, please stop by <https://eslint.org/chat/help> to chat with the team.

Is that something I’m missing?

Hello, I am trying to add

aws lambda power tuning

using cdk like here: https://github.com/alexcasalboni/aws-lambda-power-tuning/blob/master/README-DEPLOY.md#option-3-deploy-the-aws-sar-app-with-aws-cdk after adding it, the sst console is keeping stuck on

Waiting for invocations

do you have any idea about this?

Hi, I'm importing an external secret into my stack. Is there any way to access a nested value at deploy time without hitting a wall with CF tokens? I know that this can be done for a top-level property:

Copy code

secret.secretValueFromJson('password').toString()

Is there a way to do it for a nested property? (such as

account.password

)

Hey there, this is less of an sst question and more of a general cdk question. https://docs.aws.amazon.com/cdk/api/v2/docs/@aws-cdk_aws-glue-alpha.Table.html#methods This is the documentation of an aws-glue table cdk construct. The

bucket

property seems to be associated with table output. I can't quite identify how I can configure what S3 bucket the generated glue table is supposed to be looking through when using something like athena to run a query on the bucket.

Hey all. I’m running into an issue where

sst start

sst deploy

hangs at the

Deploying Stacks

stage, it looks like it is caused by the following message from debug logs:

Copy code

LoggingEvent {
  startTime: 2022-02-11T20:00:19.337Z,
  categoryName: 'cdk',
  data: [
    '2022-02-11T20:00:19.336Z proxy-agent creating new ProxyAgent instance: undefined\n'
  ],
  level: Level { level: 5000, levelStr: 'TRACE', colour: 'blue' },
  context: {},
  pid: 64731
}

And error :

Copy code

LoggingEvent {
  startTime: 2022-02-11T20:00:40.219Z,
  categoryName: 'core',
  data: [
    'deploy stack: run cdk deploy: stderr:',
    "2022-02-11T20:00:40.218Z proxy-agent cache hit with key: 'no proxy secure'\n"
  ],
  level: Level { level: 5000, levelStr: 'TRACE', colour: 'blue' },
  context: {},
  pid: 64731
}

I’m assuming this is purely related to aws cdk and not sst, but wanted to see if anyone has encountered an issue like this before.

I'm going to remove a stack hosted at my

<http://domain.com|domain.com>

on route 53 and move it to... Netlify I guess. I'll keep

<http://app.domain.com|app.domain.com>

for the SST application. Effectively splitting the static site and the application. Anyone have any thoughts about things I should watch out for?

Hi friends! Having a small issue that I can't seem to figure out. I'm working on a social image generator much like the tutorial has, but my app is using esm bundles to get top level awaits etc. The problem is that

chrome-aws-lambda

uses

__dirname

in it's code, which doesn't work when in esm. Not sure if there's an easy way around this, or if I should just have the one function not use ESM or something, either way any help would be greatly appreciated! 🙂

How would you implement a function that generates sample data in a development stack for a developer to work with? This is something that should never run in production.

Dan Van Brunt

02/12/2022, 6:28 PM

Is anyone familiar with how CDK creates stacks in a construct and what that means in CFN land in term of linkage/maintenance? Specifically interested in how one deletes these resources without the CDK CLI. Do you have to delete just the main stack and something deletes the other for you? Or these are actually completely silo’d stack which require you to delete each one independently?

Hello everyone, I am new to SST. I had to add a range key to one of the DynamoDB tables in my app. Now, I am getting the following error while deploying:

Copy code

Export dev-storage:ExportsOutputFn.... cannot be deleted as it is in use by dev-api

I tried renaming the table. But, that did not work either. Please suggest.

Hello 👋 I'm considering using SST for a new project and one of my requirements will be to provision AWS resources dynamically for customers e.g. each customer would have their own deployed lambdas / dynamoDB tables etc... I'm wondering if there is any prior art in using SST/CDK from inside a lambda?

Pablo Fernandez

02/13/2022, 2:50 PM

Has anybody wrote a way for developers to easily create sample data? And easily destroy it and recreate it? How do you do it?

Hi there, is anyone using NestJS https://docs.nestjs.com/ for their backends with SST ? if so how are you making it work together ?

I’m having an issue where I created an AppSyncApi in one project, and am trying to extend it in another project (ie, add resolvers) by importing the GraphQL like the example:

Copy code

import { GraphqlApi } from "@aws-cdk/aws-appsync-alpha";

const api = new AppSyncApi(this, "GraphqlApi", {
  graphqlApi: GraphqlApi.fromGraphqlApiAttributes(this, "IGraphqlApi", {
    graphqlApiId,
  }),
});

However, if i then try to add a unit resolver where i reference a datasource I added in the first stack it fails; also, if i try to lookup the datasource by name

Copy code

api.getDataSource('mydsName');

it also returns undefined. Any thoughts?

Hi everyone, I am trying to wrap my head around the cold start speed and how I could optimize it, my functions are around 1.8mb and I am seeing >1s cold starts I did some tests running a payload of 100 req a second on a function and it I was getting

Copy code

99th percentile: 2.042189291s
P95th percentile: 2.011754874s
P90th percentile: 1.985379375s
P50th percentile: 1.683923479s
Max : 2.042189291s
Mean : 1.571575707s
Min : 884.344166ms

The time with warm lambdas is around 100-300ms. Is 1.8mb too much? The env. is node14 with 1024mb memory and arm64 arch. I am really wondering if this has to do with the size of the function or something else.

Hey! Does anyone have any tips and tricks for finding out the "deploy hot path" for a set of cloudformation stacks to deploy? Or a dependency graph of CFN stacks? We have 18 stacks and counting and deploys are gradually slowing down so would like to debug.

Hey everyone! Is there an easy way to simplify how resources are named when they’re deployed with SST? For example I have a IAM User Group with the generated name:

dev-appname-MyStack-Admins8B360DEA-U132VR1JXSY0

. I would love to be able to set the name myself so I could name it something like:

dev-appname-MyStack-Admins

I’m building a feature which is going to be writing events to SQS from a lambda. The incoming throughput can go very high ~ 2000 req/s and these would be processed in realtime . Should I be using lambda and SQS for this or something else. Anyone processing data at such scale, how are you approaching it, should I be looking into MQTT or Kafka. I’m worried about back-pressure and throttling.
