Summary

I have a pipeline that was working fine until yesterday. Without making any changes, it started failing today with this error:

Error: The auto scaling configuration ARN you specified isn't valid. ARN: ''

Relevant

I highly suspect #33 and this change are relevant.

https://github.com/awslabs/amazon-app-runner-deploy/blob/17a435dee343fd6395a23c710ad4edebcf568a5c/CHANGELOG.md?plain=1#L12

Reproduction

Step configuration that fails:

      - name: Deploy to App Runner Image
        id: deploy-apprunner
        uses: awslabs/amazon-app-runner-deploy@main
        with:
          service: my-app-staging-app-runner-service
          image: ${{ steps.login-ecr.outputs.registry }}/my-app-staging-dotnet-backend:${{ github.sha }}
          access-role-arn: ${{ secrets.ROLE_ARN }}
          region: eu-west-1
          cpu: 1
          memory: 2

Contributing Guidelines checklist:

• A reproducible test case or series of steps -> Done, to some extent.
• The version of our code being used -> awslabs/amazon-app-runner-deploy@main
• Any modifications you've made relevant to the bug -> Nope. But there are 2.20 changes that might be relevant.
• Anything unusual about your environment or deployment -> Nope.

Update: A workaround

You can lock the version of awslabs/amazon-app-runner-deploy to 54d9f229e41b80f7cace6480c45ab6dcb1d1af0f, a version that seems to work.

In your yaml, change:

uses: awslabs/amazon-app-runner-deploy@main

to:

uses: awslabs/amazon-app-runner-deploy@54d9f229e41b80f7cace6480c45ab6dcb1d1af0f

It may be a good idea to lock the version even regardless of this issue.
