GitHub 500 Error Pull Request | Step-by-Step Troubleshooting

If you’re getting a 500 Internal Server Error when trying to create, view, or interact with a GitHub pull request, that typically means something went wrong on GitHub’s servers — but there are a few things you can check or try on your end.


🔍 Step-by-Step Troubleshooting

✅ 1. Check GitHub’s Status

Start by verifying if GitHub is experiencing issues:

🔗 Visit: https://www.githubstatus.com

If you see incidents under Pull Requests, API, or Webhooks, that’s likely the cause. In that case, just wait for GitHub to resolve the issue.


🧹 2. Clear Cache / Try Private Browsing

A stale cache or browser extension could cause page rendering issues.

  • Try opening the pull request in incognito/private mode.

  • Or, clear browser cache and cookies, then refresh.

  • Disable extensions like ad blockers or script blockers temporarily.


🔄 3. Retry the Action

Sometimes a 500 error is just a temporary glitch:

  • Try reloading the page (Ctrl + R or Cmd + R).

  • If you’re submitting a PR, try again with a new browser session.

  • For large pull requests (e.g., >10k lines of code), GitHub may time out — consider breaking it up.

🔧 4. Use GitHub CLI as a Workaround

If the web interface fails, you can use the GitHub CLI to create or view PRs:

gh pr create
gh pr view

You can install the CLI here: https://cli.github.com


📁 5. Check for Large Files or Diffs

GitHub may throw 500 errors if:

  • The PR has too many file changes or very large diffs.

  • Binary files or auto-generated files are causing problems.

Consider:

  • Adding such files to .gitignore

  • Using git lfs for large assets


📫 6. Contact GitHub Support

If the issue persists and you’ve ruled out all local causes, contact support:

🔗 GitHub Support Contact

Provide:

  • Repo name and PR URL

  • Exact time and steps to reproduce the error

  • Screenshot or copy of the error message (if possible)


🧠 Extra Tip: Check Console & Network Logs

If you’re technical, open the browser DevTools (F12) and look at:

  • The Network tab → See which request failed

  • The Console tab → Look for JavaScript errors or warnings
