win10 Firebase CLI: worked but now fails on startup

[Sentinel Two]

Hi folks

For the past few month every thing has gone fine hosting a static web site from WIn10 using the Firebase CLI.

Having recently updated npm or firebase itself I am now getting and error message that seems to be due to  Firebase credential being left undefined:

Here's what the shell now shows on start up:

################################################################################

So I can no longer deploy changes to the static site - which remains up.

Any suggested remedies?

Hey there,

Looks like a bug in the CLi to me!  The best thing to do is file an issue here:
https://github.com/firebase/firebase-tools

Make sure to include information like your Windows version, Node version, etc to help us reproduce this.  If this used to work for you but has started to break, please let us know what version of the CLI was the last working one for you.  Thank you!

Thanks Sam

I'll file the issue! 

But in the meantime is there a recommend way of rolling back to say v7.70 ?

I am fairly new to this game and have not done such before.

Cheers

If you want to downgrade to a particular version, like 7.7.0, just run:

npm install -g firebas...@7.7.0
