Unexpected String in a Json file by removing the firebase plugin

Question

When I try to remove the apache cordova plugin "cordova-plugin-firebase", I get the error "Unexpected string in JSON at position 1296" but the console don't show a file or something which help me to understand the error. Do someone have an idea?

I remove every platform and that don't help to remove this error.

The comand line:

cordova plugin remove cordova-plugin-firebase

The result:

Removing "cordova-plugin-firebase"
Unexpected string in JSON at position 1296
