Create User response code 500 (internal server error) #9
Description
Related to #8.
A user name longer than 16 characters is by default a schema violation of the database, but the length of the username of the request body is not checked. The server returns a 500 (internal server error), and a Stack-trace is printed to the console.
Expected behavior would be error 400 (bad request).
Is it possible to change the maximum length of a username in a configuration without manually changing the definition of the database relation?
