I’m not sure where I should propose this, so I’m adding this here:
The guide about deploying to Vercel from GitHub actions
https://vercel.com/guides/how-can-i-use-github-actions-with-vercel
is missing important feature about custom domains. I got an error when following the documentation, found in on GitHub discussion.
There is should be a link to this article:
https://vercel.com/guides/how-to-alias-a-preview-deployment-using-the-cli
Note: if someone is taking the time to deploy from GitHub action, he/she probably have a custom domain by now.
Another issue with docs is this issue:
https://github.com/vercel/vercel/issues/14304
It requires adding --scope <your org> to the Vercel CLI.
This can be solved by updating documentation.
