Object reference not set to an instance of an object

Purpose

PDQ Deploy or Inventory reports “Object reference not set to an instance of an object” or “NullReferenceException” errors. These errors are caused when the application tries to reference a variable and (unexpectedly) receives a NULL value. This can happen at seemingly random times.

Resolution

This error is usually a transient error that can be fixed by a simple restart of the PDQ Server.

If you continue to see this error after a restart, then it could point to some potential performance issues. In that case, click the “Submit this issue to PDQ Support” link in the error window to start a troubleshooting ticket with our support team.
