Known Issues
- Requires GitHub Copilot to be installed and properly configured
- Azure DevOps PR creation requires appropriate repository permissions and network access
- Git operations require a valid Git repository with remote configuration
- AI-generated content quality depends on GitHub Copilot model availability and workspace context
- Large repositories may experience slower performance during context analysis
Troubleshooting
Authentication Issues
- GitHub Copilot: Ensure you're signed in to GitHub Copilot in VS Code
- Azure DevOps: Run
az login in terminal or allow interactive browser authentication
- Git: Verify Git is configured with your credentials (
git config --global user.name and git config --global user.email)
Git Operation Failures
- Verify you have write permissions to the repository
- Ensure Git remote is properly configured (
git remote -v)
- Check that you're not working directly on protected branches (main/master)
- Confirm your working directory is clean or has the changes you want to commit
Git Add Fails with Ignored Files Error
If you encounter an error like:
Failed to push changes: Failed to execute git {
"exitCode": 1,
"gitCommand": "add",
"stderr": "The following paths are ignored by one of your .gitignore files..."
}
This occurs when the extension attempts to stage files that are ignored by .gitignore. The extension has been updated to automatically detect and skip ignored files. If you still encounter this issue:
- Ensure you're using the latest version of the extension
- Check your
.gitignore file configuration
- Use
git check-ignore <file_path> to verify which files are being ignored
- The extension will now skip ignored files automatically during staging
PR Creation Issues
- Confirm the repository is hosted on Azure DevOps (dev.azure.com or visualstudio.com)
- Verify you have permission to create pull requests in the target repository
- Ensure your branch has commits that differ from the target branch
- Check that no existing PR exists for the same source/target branch combination
Creating PR from Master/Main Branch
When you attempt to create a pull request while on the default branch (master/main):
- With uncommitted changes: The extension will prompt you to run "Commit and Push Changes" first, which will automatically create a new feature branch
- Without uncommitted changes: You'll receive guidance to create a feature branch and make changes before creating a PR
- This prevents accidentally creating PRs from protected branches and ensures a proper Git workflow
Remote URL Validation
- The extension automatically detects problematic remote URLs with username prefixes (e.g.,
https://user@dev.azure.com/org/project/_git/repo) during both push and pull request operations
- When detected, you'll be prompted to update to the recommended format (
https://user.visualstudio.com/project/_git/repo)
- Choose "Copy Command" to copy the git command to your clipboard:
git remote set-url origin <new-url>
- After updating your remote URL in the terminal, retry the operation
Test Generation Issues
- Ensure GitHub Copilot is active and has sufficient context
- Try selecting specific code before running the command
- Verify the file you're working with is in a supported programming language
- Check that the workspace has relevant project files for better context
