HttpError: Not Found when attempting to reference private pack

Start by reproducing the GitHub Actions workflow with the private pack reference and compare its authentication behavior with codeql package download companyname/python-queries --github-auth-stdin. Check how the init action uses the supplied token; done when the workflow can resolve the private pack without the HttpError: Not Found failure.

We're trying to reference a private CodeQL pack when running init. When this runs in Github actions, we get HttpError: Not Found.

• I've verified that we can download the pack by using codeql package download companyname/python-queries --github-auth-stdin and supply the value of secrets.CUSTOM_CODEQL_SCAN_GITHUB_TOKEN.
• I've verified that CUSTOM_CODEQL_SCAN_GITHUB_TOKEN exists as an organization secret.
• I've verified that this repo has access to the published package in the organization settings.
• I've verified that the codeql scan runs fine when I remove the custom package reference.

Is there anything I'm missing or is there a bug with the init script? I'm having trouble finding any documentation around referencing private packs for CodeQL Github actions.

Thank you.
