well, I found the response, first i use the json build from ID clients OAuth 2.0 and not the json build from service Account, and then in ID clients OAuth 2.0 i add the URL in backend section : http://localhost:8888/Callback, and it's ok

I am experiencing this issue as well in a maven project. I am not quite understanding @ptro46 comment. However, it seems to be a configuration issue from the Google console rather than the code. Can instructions be clearer and more beginner friendly please?

Hi @erikacamilleri in fact I was not using the correct json, when following their doc there are two different json generated and I was not using the correct one, taking the other it worked

Hi @ptro46
can you explain the steps that you did to fix your issue?
I follow all the steps and create the json from service-account key. But I have the follow error
it is the same stack trace
This is my configuration
The downloaded json is what i use as credential.json
Where am I doing wrong?
