Errors when integrating with API GW

[royassis]

Description

This Terraform project contains terraform-aws-modules/lambda/aws modules and resources of a Private Rest API Gateway.
After applying using Terraform Cloud, the API-GW endpoints return:

{
  "message": "Internal server error"
}

This happens only when I change the code in the source_path of the module.
And it affects only the current deployment of the apigw stage. When running the lambda from the test console of API Gateway it works, so does testing the lambda from the lambda console.
Creating a new deployment fixes it.
When looking at the previous lambda version the Resource-based policy statements looks ok.

⚠️ Note

Before you submit an issue, please perform the following first:

1. Remove the local .terraform directory (! ONLY if state is stored remotely, which hopefully you are following that best practice!): rm -rf .terraform/
2. Re-initialize the project root to pull down modules: terraform init
3. Re-attempt your terraform plan or apply and check if the issue still persists

Reproduction Code [Required]

Steps to reproduce the behavior:

locals {
  source_arn = "arn:aws:execute-api:<region>:<accountid>:<restapiid>/*/*/*"
}

locals {
  allowed_triggers = {
    APIGatewayAny = {
      service    = "apigateway"
      source_arn = local.source_arn
    }
  }
}

module "lambda_function_GetApigwResources" {
  source = "terraform-aws-modules/lambda/aws"

  function_name            = "GetApigwResources"
  handler                  = "app.handler"
  runtime                  = "python3.9"
  timeout                  = 10
  store_on_s3              = true
  s3_bucket                = <bucketname>
  s3_prefix                = "lambda-builds/"
  attach_policy_statements = true
  policy_statements        = {
    apigateway = {
      effect    = "Allow",
      actions   = ["apigateway:Get*"],
      resources = ["*"]
    }
  }
  role_path   = "/tf-managed/"
  policy_path = "/tf-managed/"
  source_path = "../src/lambda_code/describe_apigw_resources/app.py"
  tags        = {
    "map-migrated" = var.map-migrated
  }
  #  create_current_version_allowed_triggers = true
  publish          = true
  allowed_triggers = local.allowed_triggers
}

Expected behavior

API GW returns a valid response.

Actual behavior

API GW return s

{

The error is not related to the module itself. Please check logs in CloudWatch or in the Lambda console.
