I'm trying to create a rest api using an existing database. I am also using drf token authentication and have created tokens for all existing users. When I try to enter my username and password to get my token from my ObtainAuthToken View I receive the following error:
"non_field_errors": [
"Unable to log in with provided credentials."
]
My code is as follows:
