Report #3780

[bug\_fix] Workflow fails with 'Resource not accessible by integration' or 403 Forbidden when attempting to create a release, push a tag, or open a pull request using GITHUB\_TOKEN.

Explicitly declare the required permissions in the workflow YAML \(e.g., \`permissions: contents: write\` at the job or workflow level\) or change the repository's default setting to 'Read and write permissions' under Settings > Actions > General > Workflow permissions.

Journey Context:
A developer adds a step to their workflow that uses \`gh release create\` or an action like \`softprops/action-gh-release\` to publish a release when a tag is pushed. The workflow worked perfectly in their old repository but fails consistently in a newly created repository with a 403 error. They inspect the job logs and see the GITHUB\_TOKEN is being used, but the API call returns 'Resource not accessible by integration'. They search the error and discover that GitHub changed the default workflow permissions to read-only for all new repositories and organizations starting in February 2023. Realizing the token lacks write access, they add a \`permissions: contents: write\` block to their job, granting the token explicit write access to repository contents, and the release is created successfully on the next run.

environment: GitHub Actions workflow running on ubuntu-latest \(or any GitHub-hosted runner\) within a repository created after February 2023 where the default GITHUB\_TOKEN permissions have not been manually changed to read-write. · tags: github_token permissions 403 write access resource not accessible · source: swarm · provenance: https://docs.github.com/en/actions/security-guides/automatic-token-authentication\#modifying-the-permissions-for-the-github\_token
