cdk synth command should not require a GITHUB_TOKEN

[zaro0508]

I'm getting this error message that says i need a package.json file when attempting to run synth however I'm have a python project and i've already have a requirements.txt file containing the needed dependencies. I'm not sure why i need a package.json

Run youyo/aws-cdk-github-actions@v2
/usr/bin/docker run --name c3c9fab9b5f6b455f82604107fe244452_754adf --label 49859c --workdir /github/workspace --rm -e

OK. Adding a package.json file didn't fix the problem. I think real problem is /entrypoint.sh: line 95: GITHUB_TOKEN: unbound variable. Running CDK synth command does not require access to AWS however I think this error indicates that the aws-cdk-github-actions requires access?

Ran into the same issue, try including actions_comment: false

Thanks @paulmeier that worked.
