I found the following error in the log file and was wondering if this might be the reason:
Exception System.InvalidOperationException: An error occurred when trying to create a controller of type 'IndexesV1Controller'. Make sure that the controller has a parameterless public constructor. ---> System.ArgumentException: Precondition failed: The parameter 'p_ApiKey' must not be an empty string Parameter name: p_ApiKey
