What were you trying to do (and why)?

I was trying to update the cask of https://github.com/alacritty/alacritty, since the developers recently published a new GitHub release. As a first-time Homebrew contributor, I discovered the brew bump-cask-pr command and thought it would work perfectly as a simple solution for me to make the required cask changes. During this process, I was prompted to generate a GitHub personal access token for the Homebrew CLI, which I did.

What happened (include all command output)?

After generating a GitHub Personal Access Token and storing it in the HOMEBREW_GITHUB_API_TOKEN env variable, the command brew bump-cask-pr alacritty yielded the following error:

Error: FORBIDDEN: Resource protected by organization SAML enforcement. You must grant your Personal Access token access to an organization within this enterprise.

What did you expect to happen?

I expected the version of cask alacritty to be updated to 0.14.0, a commit to be created on my local machine in my fork, that commit pushed to origin, and a pull request from my fork into upstream to be automatically opened.

Step-by-step reproduction instructions (by running brew commands)

1. Using a GitHub account which is part of at least Enterprise Organization which uses SAML SSO, generate a new Personal Access Token using the link provided by the Homebrew CLI: https://github.com/settings/tokens/new?scopes=gist,repo,workflow&description=Homebrew
2. Leave all the scopes as default and pick any expiration timeframe
3. Click generate token. Copy the token and store it in the `HOMEBREW_GITHUB_API_TOKEN` env variable
4. Attempt to use a Homebrew CLI command which invokes the `GitHub::too_many_open_prs()` method. It is expected to yield the following error: `Error: FORBIDDEN: Resource protected by organization SAML enforcement. You must grant your Personal Access token access to an organization within this enterprise.`

I did a bit of research on my own and discovered the following:

• Once I properly configure SSO for the GitHub Personal Access Token being used by Homebrew, the error goes away
• Testing with two different tokens against the public GitHub GraphQL API, the following results were observed:
  • Token 1 (SSO access) - totalCount is 17 and zero errors
    
  • Token 2 (no SSO access) - totalCount is 17 and one errors
    

(all personal access tokens used in tests were deleted before posting this comment)

The count of PRs is the same with and without SSO access enabled on my GitHub Personal Access token. However, GitHub returns a null node to represent the inaccessible (but still existent) PR:

Not sure which direction the maintainers want to take with this bug. However, if only the totalCount is being considered when fetching all of a user's pull requests, perhaps any errors returned with the API response can be ignored so long as the totalCount field is present?

I'm OK with either:

• Changing to a different API that doesn't need to go over non-Homebrew repositories (though maybe such API doesn't exist)
• Ignoring any SSO (i.e. extensions contains saml_failure) errors for that specific API call only. SAML errors for other API calls are likely genuine and should continue to error.

Yes, let's do this.
