Action no longer allows environment variables to be passed as arguments

[kevin-beatdapp]

The Github runner cannot resolve the STS client hostname when the aws-region is passed as an environment variable argument:

I fixed this issue by passing in the argument manually, however 816f5cc introduced a change that broke previously working workflows.

Based on this community forum post, I believe the correct syntax for passing the environment variable as an input to the action should be aws-region: ${{env.AWS_DEFAULT_REGION}}. Your current syntax passes the region as the literal string $AWS_DEFAULT_REGION. I can add some validation around that string to provide a better error message.

The validation change is pushed to the v1 tag now, so you should get a clearer error message around the region string.
