Amazon web services – Need to perform AWS calls for account ***, but no credentials have been configured GITHUB ACTIONS

I am running a very simple github action script (see below). It has always worked perfectly well (it worked yesterday) but now all of a sudden it fails with:

  This API will be removed in the next major release.
Warning:  aws-cdk-lib.aws_stepfunctions.StateMachineProps#definition is deprecated.
  use definitionBody: DefinitionBody.fromChainable()
  This API will be removed in the next major release.

Here is the yml being run:

I checked my github secrets and they look fine, they weren’t changed in the last 4 months, I also checked my aws credentials, they are still active and working. No changes there either.
