Return raw text(without double quotes) with codeless

Hi, I’m trying to return only the hello text without double quotes, and I can not do it. Has anyone encountered this problem?

My codeless service:
image

Actual result:

"hello"

Expected Result

hello

Backendless always returns JSON as a result. so "hello" is a json representation of hello

Thanks for your answer.
Perhaps you know how I can get response without double quotes/change the response headers?

You can’t change the response type, but you can handle it on your side. There are lots of examples on the web, f.e.: https://stackoverflow.com/questions/19156148/i-want-to-remove-double-quotes-from-a-string

I do not have access to the client side.
I’m trying to verify the of my server for the vk.com callback api. To do this, I need in response to the VK POST request, return a string without quotes.
