Error on "get_user" when user doesn't exists

[fabiothz]

Wen i try to search for a user that doesn't exist, an error occurs:

{
  "detail": "list index out of range"
}

Occurs in the line below, as the API returns a empty array.

fastapi-keycloak/fastapi_keycloak/api.py

Line 833 in 28f5f7b

return KeycloakUser(**response.json()[0])

A suggestion would be to check before instantiating the object:

response_json = response.json()
return KeycloakUser(**response_json[0]) if len(response_json) else None

This way the API will allow me to check if a user exists in keycloak.
What do you think?

Hey @fabiothz. Nice catch, this really shouldn't happen.

Personally, I would expect an error to be thrown here. Something like a UserNotFound exception. This would be the most explicit and customizable behavior I can think of. I would wait for @JonasScholl opinion on this

I believe this can now be closed! @fabiothz Are you still experiencing the issue with the latest release?
