Deployment - registerUser API error

Overview

Message Source Source:

Error: userName [user] is already registered for appName [myApp] with app uuid [example_uuid]

Potential Causes

The error would not cause any issues.  A user can only be registered once for each run of the Runtime, it is possible that the runtime is still running, and relaunching the window in which the registerUser API is run is causing this error to occur as the user has already been registered (in the current runtime session).
