• This 404 error is from GitHub, and GitHub doesn't give us any more informations about scopes for the gist endpoint (for some reason). But we can safely assume, as it happens a lot, that "Error: Not Found" (404) is because the user hasn't granted their HOMEBREW_GITHUB_API_TOKEN the gist scope.
• Fixes Improve error message for GitHub API token permission failure #13988.

Before:

$ HOMEBREW_GITHUB_API_TOKEN=<token_without_gist_scope> brew gist-logs -p logrotate
Error: Not Found

After:

❯ HOMEBREW_GITHUB_API_TOKEN=<token_without_gist_scope> brew gist-logs logrotate
Error: Your GitHub API token likely doesn't have the `gist` scope.
Create a GitHub personal access token:
https://github.com/settings/tokens/new?scopes=gist&description=Homebrew
echo 'export HOMEBREW_GITHUB_API_TOKEN=your_token_here' >> ~/.zshrc

These are in nested modules/classes so need to be fully qualified.

Thanks @Bo98, I hadn’t seen the CI failures yet.

Does no one here sleep??

That'll be on my todo list somewhere.

@Bo98 I thought we talked about this: add a help wanted issue and someone might sleep for you so you don't have to 😂
