I am working on a fastAPI server based project and till now everything worked fine. But during testing one of the endpoints, I wanted to authenticate my login, so I generated an access token. But when I try to authenticate, I am thrown with an error

auth errorError: Unprocessable Entity

I am unable to figure out how to fix this. I am truly lost as to what is to be done.

The locked endpoints in my project

edit: I have fixed the path and added a '/' after login to make it 'auth/login/' so now during my try to test the end point it shows only 401 error, but still the same 422 error when trying to authenticate. Also still don't know why it asks me client id and client secret.
