I'm having trouble setting a customDomain in a StaticSite. Here's the code:

Copy code

import * as sst from "@serverless-stack/resources";
import { StaticSiteErrorOptions } from "@serverless-stack/resources";

export default class MyStack extends sst.Stack {
  constructor(scope, id, props) {
    super(scope, id, props);

    // Create a HTTP API
    const api = new sst.Api(this, "Api", {
      customDomain: {
        domainName: "<http://api.blah.ca|api.blah.ca>",
        hostedZone: "<http://blah.ca|blah.ca>"
      },
      routes: {
        "GET /": "src/lambda.handler",
      },
    });

    // Show the endpoint in the output
    this.addOutputs({
      "ApiEndpoint": api.url,
      "CustomDomainUrl": api.customDomainUrl,
    });

    const site = new sst.StaticSite(this, "Nuxt Site", {
      path: "frontend",
      buildOutput: "dist",
      buildCommand: "npm run generate",
      errorPage: StaticSiteErrorOptions.REDIRECT_TO_INDEX_PAGE,
      customDomain: {
        domainName: "<http://dev.blah.ca|dev.blah.ca>",
        hostedZone: "<http://blah.ca|blah.ca>",
      },
    });

    this.addOutputs({
      "CloudFront URL": site.url,
    })
  }
}

The failure message is:

Copy code

MarkDev-serverless-stack-test-my-stack | CREATE_FAILED | Custom::SSTBucketDeployment | NuxtSiteCustomResource71AA1EA4 Received response status [FAILED] from custom resource. Message returned: 'NoneType' object is not iterable (RequestId: 63a4abb9-d153-4bb3-9962-b75b5f978c38)

If I comment out the customDomain passed into the StaticSite, it works fine, but not under the domain I want to use.

Does it work for the custom domain in the sst.Api?

Mark Fox

10/25/2021, 9:26 PM

Yes. The API bit works great. Sorry. That's why included it.

Frank

10/25/2021, 10:37 PM

Hey @Mark Faulkner, if you now uncomment the

customDomain

, does re-deploying it work now?

Mark Fox

10/25/2021, 10:47 PM

Trying it now.

Mark Fox

10/25/2021, 11:14 PM

Afraid not. Result is the same:

Copy code

MarkDev-serverless-stack-test-my-stack | CREATE_FAILED | Custom::SSTBucketDeployment | NuxtSiteCustomResource71AA1EA4 Received response status [FAILED] from custom resource. Message returned: 'NoneType' object is not iterable (RequestId: 63a4abb9-d153-4bb3-9962-b75b5f978c38)

Do I have to

npm update

something?

Frank

10/25/2021, 11:15 PM

I see. Maybe lets take a quick look at the CloudWatch logs for this custom resource. That should tell us the root cause.

Frank

10/25/2021, 11:21 PM

Here’re the steps to pull up the logs: 1. go to ur CloudFormation console 2. look for and select the stack

MarkDev-serverless-stack-test-my-stack

3. select the

Resources

tab 4. look for the resource of type

AWS::Lambda::Function

and with

S3Handler

in the logical id. 5. copy the physical id 6. go to ur CloudWatch console 7. select log groups 8. look for the log group with function name from step 5 9. select the log group 10. select the latest log stream 11. paste all the logs here

Frank

10/25/2021, 11:22 PM

sorry for the long list of steps… navigating within AWS console can be a bit of work

thdxr

10/25/2021, 11:23 PM

I actually click through to the function page and then click "view logs" from their monitoring tab

Mark Fox

10/26/2021, 2:20 PM

Thanks, and for the long list of steps too. I'll see what I can find.

Mark Fox

10/26/2021, 3:31 PM

There are no resources of type

AWS::Lambda::Functions

with

S3Handler

in the logical id.

Mark Fox

10/26/2021, 3:37 PM

Looking at the events, here's the last success, followed by the first errors:

thdxr

10/26/2021, 7:59 PM

can you verify the bucket for the deploy exists?

Mark Fox

10/26/2021, 8:08 PM

That would be named something like

MarkDev-serverless-stack-test-my-stack

, right?

thdxr

10/26/2021, 8:09 PM

you can look to see what your cloudfront distribution is pointing at

thdxr

10/26/2021, 8:09 PM

and if it's there, I'm curious what's in it

Mark Fox

10/26/2021, 8:14 PM

There's no CloudFront distribution and no S3 bucket. When I run a deploy, the S3 bucket appears, a CloudFront distribution for the dev API appears, as does the S3 bucket markdev-serverless-stack-t-nuxtsitebucket0f527c37-1cmtwvhth1lkr, but it all disappears the deployment is rolled back.

Mark Fox

10/26/2021, 8:16 PM

In case it matters, I never saw any objects in the deployment S3 bucket while it existed.

thdxr

10/26/2021, 8:18 PM

hm I'm stumped, maybe Frank has an idea

thdxr

10/26/2021, 8:18 PM

afaik that script isn't effected by custom domains so wonder why it's failing

Mark Fox

10/26/2021, 8:21 PM

I'll try just running locally (ie.

npx sst start

Mark Fox

10/26/2021, 8:30 PM

And it works fine, but that's without the custom domain.

Mark Fox

10/26/2021, 8:30 PM

So where do the SST Python files end up? Could I modify them to add more debugging output and run another deploy?

Frank

10/26/2021, 8:33 PM

Thanks for looking into this @thdxr.

Frank

10/26/2021, 8:33 PM

Hey @Mark Fox, lemme take a quick look at the CW logs u shared.

Mark Fox

10/26/2021, 8:34 PM

No problem. Thanks to both of you for looking at this.

Frank

10/26/2021, 8:35 PM

np! Btw, here’s the code of the python file that’s failing https://github.com/serverless-stack/serverless-stack/blob/master/packages/resources/assets/BaseSite/custom-resource/s3-handler.py

Frank

10/26/2021, 8:36 PM

Btw, which version of SST r u using?

Mark Fox

10/26/2021, 8:38 PM

0.1.0

Frank

10/26/2021, 8:39 PM

Can you try running

npx sst --version

Mark Fox

10/26/2021, 8:40 PM

Oops. Sure:

Copy code

SST: 0.45.1
CDK: 1.125.0

Frank

10/26/2021, 8:43 PM

Can you update SST to

0.49.2

and give it another try?

Frank

10/26/2021, 8:44 PM

We fixed an issue that might be related to this.

Frank

10/26/2021, 8:44 PM

You can update using:

Copy code

$ npx sst update 0.49.2
$ yarn sst update 0.49.2

depending on the packager u r using

Mark Fox

10/26/2021, 8:47 PM

It's updating to latest now.

Mark Fox

10/26/2021, 8:51 PM

The deploy is running now.

Mark Fox

10/26/2021, 9:48 PM

And that fixed that problem. Thanks! But it didn't upload anything to the bucket. That might just have been my mistake. I'll make a point to upgrade before I bother anyone next time. On the plus side, I have a better understanding of what is going on under the hood.

Frank

10/26/2021, 9:49 PM

Oh nice… glad u r making progress.

Frank

10/26/2021, 9:50 PM

No worries at all!
