UnhandledPromiseRejectionWarning: FirebaseError: Task

See original GitHub issue

Environment info

firebase-tools: Version: 7.3.2

Platform: macOS: 10.14.6

Test case

I tried to upload files to firebase hosting with firebase deploy --only hosting which throws error.

Steps to reproduce

I tried to upload files to firebase hosting with firebase deploy --only hosting. In my files I have symlinks, one of the symlink points to a file that doesn’t exist. This causes error.

Expected behavior

Upload files without any issues.

Actual behavior

Throws UnhandledPromiseRejectionWarning: FirebaseError: Task

=== Deploying to 'project'...

@tuananhlhpnd99 Yeah, that’s pretty a head ache for developer, also wastes hours and hours of time to find out the right issue.

@Firebase @Memeriaj team, If you guys can show a proper warning or error message will help to save the time instead of unhandled promise reject warning

I suffer from this issue too and it turned out that I left an unused symlink in the public folder. After removing that symlink, things worked just fine. I think that is time to close the issue.
