We’re getting an odd bug in a production server. We have a stack trace, but no line numbers, so I know the method where the bug is, but not the exact line. It’s complaining of a ‘Object reference not set to an instance of an object.’ Something is null.

After looking at the code, the only two potential culprits that I can see are the two consecutive lines that read: 

string currentPath = this.Request.CurrentExecutionFilePath; string[] parts = currentPath.Split('/');

which would throw if Request was null, or if the CurrentExecutionFilePath of the Request was null. I’m not really clear on when (or even if) this can happen. Am I barking up the wrong tree here? (This code seems to be running during the Load portion of the page lifecycle).

  1. Do you have PDB output enabled for your release build?

    If you do you would only need to deploy the pdb to your production server to get line numbers in your stack trace.

    (pdb and dlls have to match)
