Now in case of any error in my cloud code I see "timeout" error in the respond message. Is there a way to get an actual error message?

I use UE, here is picture of request code and respond. I have an error in cloud code "start_match"

in "start_match" is row cache.put("a_location", 1); and debuging shows

  "message": "Function put does not accept parameters (string,number). (event/start_match.js#96)"
