An error occurred while starting the trigger.

I cannot add a screenshot due to my reputation. Here is the error I received:

Error source: SqlClient.NET data provider Error message: An error occurred while starting the trigger. The batch was aborted, and the user's transaction, if any, was discarded.

Here is my stored procedure.

-- information was not logged.

    -- a transaction is in an uncommittable state.
