Guarantee JSON Response

[Asaf Peleg]

is there a way to guarantee that spray will always return a json response.  I found through testing that sending a very large or negative content-length results in a canned plain text response back from spray?

Logs show this : [WARN] [05/12/2016 17:14:28.690] [on-spray-can-akka.actor.default-dispatcher-9] [akka://on-spray-can/user/IO-HTTP/listener-0/3] Illegal request, responding with status '400 Bad Request': Illegal `Content-Length` header value

Response is: Illegal `Content-Length` header value

Hi Asaf

The default rejection handler and exception handler in Spray will produce plain text output. If you want those to produce JSON, you will need to write custom versions of those. 

Some doc links:

Some examples of people who have wrapped the default rejection handler in JSON:

Hope this helps
