Django OAuth Toolkit - AttributeError: get_full_path

Question

I'm trying to setup the token authentication but when I try to get a token, i get this error. Endpoint is '/o/token/'. When i POST a wrong client_id or a wrong grant_type, i receive the response i expect:

{
    "error": "invalid_client"
}

or

{
    "error": "unsupported_grant_type"
}

But when sending the actual data (grant_type, client_id, username, password) it crashes:

Internal Server Error: /o/token/

AttributeError: get_full_path
[12/Mar/2020 07:51:30] "POST /o/token/ HTTP/1.1" 500 177519

Somewhen token.py creates a 'oauthlib.Request' which has no property 'get_full_path'. Has someone ever had the same problem or might know what could cause this? I run out of ideas :(
