Flutter – Failed to parse JSON response from Firebase CLI. JSON response: FormatException: Unexpected end of input (at character 1)

I am trying to setup my firebase project with flutter app. I was already using flutter successfully with no problems and was using firebase before they added this CLI method.

I have successfully installed CLI, logged in and made the ‘firebase init’ command and no problems appeared also my projects appear when I use the ‘firebase projects:list’ command.

Then I used the ‘dart pub global activate flutterfire_cli’ command and no errors and the problems happens with ‘flutterfire config’ at the root of the project and the error message in the title appears and a firebase.js files pops up in my editor (the content of it is shared below).

I have tried making a new project, new firebase account and all the solution on the web but with no progress.
