I have developed an SP Feature in C# and tested in development environment, confirming it is functioning correctly.
When I publish to production and enable on a site, I just get a single line in the ULS log when it triggers:
Loading and running the event receiver class TCBSEmailHandler.TCBSMetadataExtractionEventHandler.TCBSMetadataExtractionEventHandler from assembly TCBSEmailHandler, Version=22.214.171.124, Culture=neutral, PublicKeyToken=49f071f6ad2c11c6 failed. Object reference not set to an instance of an object.
What can I do in the production environment to debug this error?
A similar question of mine regarding debugging in development was answered here, but I'm not sure if/how I could apply similar logic to a deployed solution.
