Common exceptions from GQI extensions

The following exceptions can commonly occur when developing GQI extensions. For each exception, a number of known common causes are listed, but these are not exclusive. Other causes may exist.

System.ObjectDisposedException: The CancellationTokenSource has been disposed

  • Data is requested via GQIDMS after the session is closed. After OnDestroy is invoked, the GQIDMS object is disposed of, and it can no longer accept new requests.

System.Threading.Tasks.TaskCanceledException: A task was canceled

  • A GQIDMS request is still in progress when the session is closed. When OnDestroy is invoked, any ongoing requests are canceled.
