Hi @w-sx

Thank you for contributing this PR.

Here are some small suggestions that may help you:

1. Fill out the PR description as much as possible, although you already provided useful details in Workflow failed to build #39.
2. Linking a pull request to an issue using a keyword, When you link a pull request to the issue the pull request addresses, collaborators can see that someone is working on the issue. When your linked pull request is merged into the repository's, its linked issues will automatically be closed. Keywords you can choose include fixed, closed, close, etc. E.G. Closed Workflow failed to build #39

Cheers,
Cary
