Please add following to the documentation: 1) About caching functions. (After changing the function, at least 5 minutes must pass, otherwise you will not see the changes) 2) About bypassing circular dependencies 3) It is necessary to duplicate the CORS headers in the lambda function response (if it hasn't been mentioned anywhere else) It would have saved me 3 days of searching. I think it should help the others a lot too.

I finally understood the main problem. The CORS error says that even in the preflight request we are getting

Access-Control-Allow-Origin: *

, but there is a different value there.

Copy code

allowOrigins: [
          "<http://localhost:3000>",
          "<https://domain1>",
          "<https://dev.domain1>",
        ],

Hello everyone ! I was wondering if someone tried to use injection like inversifyjs with SST ? I tried to implement an API with a route targeting the code below but got an error like it doesn't find/resolve but it works if I instantiate the class without injection

Copy code

export interface IService {
  handle(event: APIGatewayProxyEvent): Promise<APIGatewayProxyResult>;
}

@injectable()
export class TestInject implements IService {
  public async handle(event: APIGatewayProxyEvent) {
    console.log('test inject');
    return {
      statusCode: 200,
      headers: { 'Content-Type': 'application/json' },
      body: JSON.stringify({ success: true }),
    };
  }
}

const service = myContainer.get<IService>(TYPES.IService);
export const handle = service.handle;

Result:

Copy code

Unhandled Promise Rejection     {"errorType":"Runtime.UnhandledPromiseRejection","errorMessage":"TypeError: Cannot read property 'name' of undefined","reason":"TypeError: Cannot read property 'name' of undefined","promise":{},"stack":["Runtime.UnhandledPromiseRejection: TypeError: Cannot read property 'name' of undefined","    at process.<anonymous> (file:///home/uncharted/projects/my-api/node_modules/@serverless-stack/aws-lambda-ric/lib/index.js:34:23)","    at process.emit (events.js:376:20)","    at processPromiseRejections (internal/process/promises.js:245:33)","    at processTicksAndRejections (internal/process/task_queues.js:96:32)"]}

Hey everyone, I want to create a route on my Python API that uses a large package (Pandas) that none of my other routes need. Is there a standard way to do this in SST so that my other packages don't all end up with Pandas as a dependency. If I add it to the requirements.txt for my api that gets loaded it will end up everywhere which would be a cosmic waste of resources. Any suggestions would be greatly apprciated

Is there any plan to support .net 6 as it is officially supported runtime in aws lambda now . Also how many dotnet users here.

I’m building an api which Stripe will redirect to in order to subscribe the user after confirming payment details. I have an AuthStack setup which allows for the use of AWS IAM authorization when making requests to my api. I am wondering, if the user has previously authenticated via IAM in the browser, will the authorization still be valid if I direct the user to Stripe, then Stripe redirects back to the api (protected by IAM authorization)?

I’m interested in refactoring some existing resources to a separate stack, notably a

. Are there any examples/guides on how to do this with SST?

So what are you guys doing to keep your lambda code organized? Any specific frameworks or patterns? So far I'm going freestyle, and it works quite well, but I'm not sure if I'll be able to still handle the project when it gets much larger.

Hey there, following up here. Still dealing with this issue. My latest comments have narrowed down the root cause of the issue. https://serverless-stack.slack.com/archives/C01JG3B20RY/p1647536454769239?thread_ts=1643127297.129100&cid=C01JG3B20RY There's also a discrepancy in the documentation at this link: https://docs.serverless-stack.com/constructs/Function#python-runtime-1 Specifically: "You can override this behavior by passing in the

installCommands

through the FunctionBundlePythonProps." This doesn't seem to be correct, passing in installCommands doesn't stop the step that installs poetry, pipenv, or pip. It's not an override, because the script with the passed in commands is passed in afterwards, as seen here in this dockerfile https://github.com/serverless-stack/serverless-stack/blob/master/packages/resources/assets/python/Dockerfile.dependencies This bundling behavior leads to certificate errors, with no clear way for resolution. If it was possible to have custom commands run before external deps are pulled in order to add required certs, then I believe this issue would be alleviated

probably a dependency issue but when I start a new project and a create an

sst.Bucket

inside a class that extends

cdk.Construct

I get the following error

new Bucket(_this_, "Bucket");

Copy code

Type 'ConstructNode' is missing the following properties from type 'Node': _locked, _children, _context, _metadata, and 6 more.

here are the deps:

Copy code

    "@aws-cdk/aws-iam": "^1.149.0",
    "@aws-cdk/aws-ssm": "^1.149.0",

    "@types/node": "<15.0.0",
    "aws-cdk-lib": "2.15.0",
    "typescript": "4.4.4"
  }

any pointers please?

Is it possible to configure multiple custom domains on the

sst.StaticSite

construct? I’m using it to build a multi-purpose reverse proxy/redirect engine for several of our domains. StaticSite provides some convenience I would like to leverage, but I also need the CloudFront distribution to allow multiple custom domains. When I configure it directly on the

cfDistribution

I get an error telling me to use

customDomain

on the

sst.StaticSite

but this doesn’t appear to allow multiple domains. Any suggestions?

Hello. I was just updating sst from version 0.65.5 to 0.69.2 and now when I run

sst test

I get an error:

Cannot find module 'regenerator-runtime'

And also Typescript is not able to find jest anymore. Is there an upgrade instruction somewhere?

I'm trying to use

prisma

along with

sst

in a simple API. Prisma requires access to this

schema.prisma

file -- how can I include that extra file to be packaged up with the code during deployment?

hey guys, using a custom domain and having some issues. // Create the API this.api = new sst.Api(this, "Api", { customDomain: scope.stage === "prod" ? "example.com" : undefined, ... // Show the API endpoint in the output this.addOutputs({ ApiEndpoint: this.api.customDomainUrl || this.api.url, }); I can see the hosted zone in route 53 and it looks fine, but i get this error running npx sst deploy --stage prod [Error at /prod-Example-api/Api] Found zones: [] for dns:com, privateZone:undefined, vpcId:undefined, but wanted exactly 1 zone Found errors It seems you are configuring custom domains for you URL. And SST is not able to find the hosted zone "com" in your AWS Route 53 account. Please double check and make sure the zone exists, or pass in a different zone. Any ideas? 🙂

still struggling. im on the frontend bit now. been trying to figure this out for a while now 😕 lol. I already have a hosted zone but its already got a NS and SOA, not sure if this is causing me issues.
