So, I'm learning DjangoRF through a Udemy course in which we build an API with a token authentication. All code written, I launch my server, I try to login via example client and this error occur:
Status Code: 400
{'non_field_errors': ['Unable to log in with provided credentials.']}
This happen with both user and superuser.
Then I try to login from the admin page in the Browsable API and the superuser works, the user not.
I'm new to this framework and even with Python so i actually can't figure aout a solution.
CLIENT:
import requests
def client():
credentials = {"username ": "user", "password": "user"}
response = requests.post('http://127.0.0.1:8000/api/rest-auth/login/', data=credentials)
print('Status Code: ', response.status_code)
response_data = response.json()
print(response_data)
if __name__ == '__main__':
client()

Obviously I'm sure that credentials are always correct (don't mind that the password does not respect the permissions in setting.py, I uncommented permissions in order to post here)
Thanks you.
