Unable to perform any actions with the REST API

Getting advice
1

Hi! I’m having problems performing any actions whatsoever with the REST API in my python script. At the moment, just for testing I want to login and create a user (or a client), this is what I have so far, both with direct requests, and with the python-keycloak library.

Directly with requests, trying to create a client:

import requests
import argparse
import ast


def get_token():
    url = f"{kc['SERVER_URL']}realms/my-realm-name/protocol/openid-connect/token"
    params = {
        'client_id': 'admin-cli',
        'client_secret': kc['CLIENT_SECRET'],
        'grant_type': 'client_credentials',
        #'username': kc['USER'],
        #'password': kc['PASS']
    }
    x = requests.post(url, params, verify=True).content.decode('utf-8')
    print(x)
    print('\n')
    return ast.literal_eval(x)['access_token']
    # return requests.post(url, params, verify=False).content.decode('utf-8')


def create_client():
    url = f"{kc['SERVER_URL']}admin/realms/my-realm-name/clients"
    headers = {
        'content-type': 'application/json',
        'Authorization': 'Bearer ' + str(get_token())
    }
    params = {
        "clientId": "testclient",
        "id":"3",
        "name": "testclient-3",
        "description": "TESTCLIENT-3",
        "enabled": True,
        "redirectUris":[ "\\" ],
        "publicClient": True
    }
    x = requests.post(url, headers=headers, json=params)
    print(x)
    print(x.content)
    print(x.text)
    return x.content


create_client()

With python-keycloak library creating a user:

from keycloak import KeycloakAdmin, KeycloakOpenID
from .settings import KEYCLOAK as kc


keycloak_access = KeycloakAdmin(server_url=kc['SERVER_URL'],
                                username=kc['USER'],
                                password=kc['PASS'],
                                realm_name=kc['REALM'],
                                client_id=kc['CLIENT_ID'],
                                client_secret_key=kc['CLIENT_SECRET'],
                                user_realm_name='master',
                                verify=True)

print(keycloak_access)
# Add user
new_user = keycloak_access.create_user({
                    "email": "example@example.com",
                    "username": "example",
                    "enabled": True,
                    "firstName": "Example",
                    "lastName": "Example",
                    "realmRoles": ["test_role", ],
                    "attributes": {"example": "1,2,3,3,"}})

Both login correctly (I get the token etc.) but when I perform any actions I get a 403 with “unknown error”.

Any clue on why this is happening? The clients have full scopes active, they are confidential type with service accounts enabled, etc.
