Caused by: retrofit.RetrofitError: method POST must have a request body

Question

I am using retrofit to make a post api call, I am getting the following error while trying to hit the endpoint.

     Caused by: rx.exceptions.OnErrorNotImple         


        

Answer 1

@Body String emptyBody wasn't working for me as backend server I was working with, was returning Bad request and not accepting empty string as a body.

I've just sent empty JSON instead of empty String

@POST("/some/url) Observable doThing(@Body JsonElement empty);

and then I just called my method like this:

doThing(new JsonObject());

Hope it will help if someone has similar problem.
