Can’t configure credentials with GitHub App

[slocoro]

Describe the bug

I have a python script that triggers a Github Actions workflow using a Github App installation. The triggered workflow fails with the following message when trying to configure AWS credentials:

Error: Could not assume role with web identity token file: Unable to validate tags

Weirdly, when I use a PAT instead of the Github App installation I'm able to configure the credentials.

Found this similar looking issue #930 but wasn't able to solve my problem.

Any help will be greatly appreciated :)

jobs:
    steps:
      - name: Configure AWS credentials
        uses: github-actions/configure-aws-credentials@v4
        with:
