I am having an issue and i'm stumped so I'm hoping someone can help.

It looks like structuremap is having an issue building the controller. I know everything is built properly because a) this has been in production for years and b) the link i'm following when I get the error is from the same controller.

I am unable to reproduce this on my dev machine. Could anyone give me some clues?

  • Please show some relevant code. Also please see [this post](https://stackoverflow.com/questions/4660142/) – Aleks Andreev Sep 20 '17 at 17:04
  • I am honestly not sure how to show relevant code. I click a button in a form in my view which calls a method in my controller. But for some reason the method in my controller is not being hit due to this structuremap error. I'm familiar with a null reference exception but this one is occuring in external code so I don't know how to troubleshoot it. – Georgia Sep 20 '17 at 17:34
