ASP.NET Web API: Non-descriptive 500 Internal Server Error

Question

As title says, I’ve got 500 Internal Server Error from GET request to an IQueryable action. The body of the error is empty. That error happens after my action returns result

Answer 1

I had the same problem, but the source of it was slightly different: I set the CORS policy incorrectly and that gives me 500 Internal server error, but since CORS was not working, the Access-Control-Allow-Origin header was not presented in response and browser can't read the actual response

I solved it with ChromeDevTools option Copy as cURL which allows me see the response and understand the source of error
