HTTP Status 401 : Cannot pass null or empty values to constructor

The server is expecting a query param but you are sending the wrong value in it.

So simpler answer is:

We need to send a valid query param what the server is expecting.

The actual line that produces the exception is here. The relevant code where the user object is created is here.

So my best guess is that you have a null password field for the user in the database.

Note that if you are posting an error like this it's a lot easier to answer if you give the stacktrace and the relevant debug output from the server log.
