Firebase Cloud Functions : Failed to read credentials from file

Question

Due to new Firebase Cloud Functions (version > 1.0). I only need to call

admin.initializeApp();

Without any parameters.

However when I did like that then run firebase deploy --only functions , this error occurred :

Failed to read credentials from file G:\projects\ANOTHER_PROJECT\ANOTHER_PROJECT.json: Error: ENOENT: no such file or directory, open 'G:\projects\ANOTHER_PROJECT\ANOTHER_PROJECT.json'

Answer 1

I found out the issue was that i had GOOGLE_APPLICATION_CREDENTIALS environment variable defined which was pointing to json file which did not exist and i had long deleted.

I deleted the GOOGLE_APPLICATION_CREDENTIALS env variable. Restarted the terminal and then firebase deploy --only functions worked flawlessly.

Answer 2

In my case, I was adding the " in the path, I was using the windows terminal.

I hope it works for someone.
