I added drupal module "Oauth2" in order to test access by tokens. I created a consumer and got his uuid and client_secret by which I tested, using postman post method, the genretation of my first token,but it failed by 403 access forbidden(see the capture bellow):
I tried to test a simple connexion (by admin account) to my user login using the post method, but it failed as well (see the capture bellow):
Seems like there is an issue with the post method
PS: I've already enabled POST for my endpoint at /admin/config/services/rest.
Thanks in advance!
