Firebase CLI always shows Error: Invalid project id: \

Question

Every time I use a firebase command this error occurs:

...\WEBRTCTest\FirebaseRTC> firebase use --add

Error: Invalid project id: \.

\WEBRTCTest\FirebaseRTC> firebase use --clear

Error: Invalid project id: \.

The error occured after I accidently run the command:

firebase use \

Prior to that all was working fine.

I tried to reinstall firebase-tools using npm and also re-cloning the example project from github. Also tried to logout using firebase logout but it gives me the same error:

\WEBRTCTest\FirebaseRTC> firebase use --clear

Error: Invalid project id: \.

I´m thankful for any idea as i´m stuck right now.

It seems Firebase CLI can get into a bad state if you accidentally use an invalid project name, then all commands will fail, even firebase use --clear (I'm using version 8.2.0)

This happens even if there is no .firebaserc file.

I got it to work by finding a valid project name in my Firebase Console on console.firebase.google.com and then run the firebase command use --clear but overriding the active project with the --project parameter indicating a valid project name, like this:

$ firebase use --clear --project="myvalidprojectname"
Cleared active project.

Run firebase use --add to define a new project alias.

Then subsequent commands will run smoothly.
