Addititionally your JS code indicates (DomContentLoaded) that you appear to be doing a code to token exchange in the front end, which will leak you private client_secret to the world.

Yes I have refresh a new code and it does work really well.

This code was for testing purposes but I will leave all my code in a secure file of course

Thank you for your answer !
