I having some issues with a GH action, it keeps telling me "unable to validate AWS credentials - see https://pulumi.io/install/aws.html for details on configuration" when I test the same credentials locally I do not see the issue.

Add in some debug to confirm the creds you're using. It may be that there's a default profile missing, or an incorrect default profile set up...

is there anything specific in the Pulumi.dev.yaml I should be setting?

Only if you want to hard-code creds.

@witty-barista-69390 how are you setting credentials?

I think you were right the profile I was using was jacking it up
