Hey everyone,
I am trying to create users via the REST-API and I am stuck.
When I try to post a user representation to Keycloak (after successfully
logging in over the API) via script (Python using the requests
framework) I get a 500 back and in the logfile of my Keycloak instance I
find:
10:50:40,268 ERROR [org.keycloak.services.error.KeycloakErrorHandler] (default task-4)

When I try to create a user via Postman (after logging in) with the user
being:
{"username": "testuser1", "enabled": true,
"attributes": {"ito_BinderLevelID1":

I get a 201 but when I try to look up the user via the Web GUI User Page
tells me "*Error!* An unexpected server error has occurred"
and I find in the logfile:
