IIS Changing Error Page Responses

Question

I have an MVC application that is running on IIS. I have created a custom exception filter handler that returns a custom JSON object. When I run it locally everything works correctly.

However, when I deploy it to IIS the correct HTTP Status Code is returned, but instead of getting my custom JSON object, I am getting a plain text response that says "Bad Request" or "The resource you are looking for has been removed, had its name changed, or is temporarily unavailable."

In my web config, I have added:

<customErrors mode="Off" />

and

<httpErrors>
  <clear />
</httpErrors>

Any suggestions would be greatly appreciated.

Thanks!

I found the solution. I needed to add errorMode = "Detailed to my httpErrors tag.

<httpErrors errorMode="Detailed">
  <clear />
</httpErrors>
