Asp.net Web API returns non-descriptive error 500
12,457
Solution 1
Had the same problem.
For me adding the
GlobalConfiguration.Configuration.IncludeErrorDetailPolicy = IncludeErrorDetailPolicy.Always;
in the WebApiConfig
Register
method helped.
After that I got nice detailed info about the error.
Here is some more info on MSDN

If it is a WCF webservice, you will have to turn the IncludeExceptionDetailInFaults flag of the ServiceBehavior attribute to true for the error to appear the way you want.

In my setup I get error 500 if anything goes wrong with my Web API request.
For instance with this simple code.
public IQueryable<Article> Get(){ throw new Exception("error"); return db.Articles; //yeah i know.. unreachable, not the point }
What I expect(and what happens in a regular MVC controller):
What I get (in Web API):
My web config:
<customErrors mode="Off"/> <compilation debug="true" targetFramework="4.5"> //under webserver <httpErrors errorMode="detailed"/>
The app pool is running 4.0 in integrated mode. 32-bit applications are enabled.
How can I get the error to surface in the browser? Or at the very least during debugging?
