Terraform-provider-aws: resource/aws_lamba_function - possible regression w/3.17.0 on GovCloud

[pjaudiomv]

After the release of 3.17.0 all my pipelines using lambdas started to fail. I suspect this has to do with the new lambda code signing resource/data source however I am not using this or any new feature from current release.

Panic Output

Expected Behavior

the provider should process my lambda without error

Actual Behavior

terraform dies with error

Error: error getting Lambda Function (test-lambda) code signing config AccessDeniedException: 
    status code: 403, request id: fghce9-fhjde1-4394-8e11-04fhjd174612

Steps to Reproduce

1. Run a plan or apply with above code snippet on GovCloud

Important Factoids

This happens on a plan or an apply and did not happen previous to 3.17.0 release.

Terraform has also blown up for me when using localstack. However, I get a different error of 404 because the CodeSigning related endpoints do not exist in Localstack.

Is there a way to by-pass this checking?

[rayjlinden]

I am able to work around this issue by pinning to last version of the provider:

terraform {
  required_providers {
    aws = "<= 3.16.0"
  }
}

[dawidmalina]

I have same issue with AWS China and I can confirm that pinning to 3.16.0 solve the issue.

Please note that we have a fix for this pending (https://github.com/hashicorp/terraform-provider-aws/pull/16412), we are just working with the Lambda service team to confirm some details before merging. We hope to have this resolved in some manner later today or tomorrow. 👍

The fix for this resource to (for now) skip the problematic API call in AWS GovCloud (US) and AWS China has been merged and will release with version 3.18.0 of the Terraform AWS Provider, likely in the next 24 hours.

For folks using LocalStack, we will probably need a separate fix due to the implementation. Please create a new bug report following the issue template (most importantly with the full terraform apply error output) and we can take a look at resolving that issue.

[rayjlinden]

Damn. At least I have the workaround of using a pinned version of aws
provider.

The bug is obvious if you even attempt to load a lambda into localstack -
which clearly must not be part of your test suite. Do you have any testing
with localstack? In any case, if simply complains it is getting 404 errors
for the new endpoints.

I’ll try to create a new issue this evening. Of course, I tried yesterday
and the template never let me submit.... guess I’ll debug that next...

This has been released in version 3.18.0 of the Terraform AWS provider. Please see the Terraform documentation on provider versioning or reach out if you need any assistance upgrading.

We have just pulled 3.18 but are still getting the same error. We are moving back to 3.16 in the meantime.

[frostymelonade]

Can confirm we are still getting error in US East 1 with 3.18

[thomasmoormann1903]

Same with eu-central-1. 3.16 works
