Hi Team,

What is the return value of cowboy_req:reply? {ok, Req2} or Req2.

The document says the below, but the real return value is Req2.


{ok, Req2} = cowboy_req:reply(200, [
    {<<"content-type">>, <<"text/plain">>}
], "Hello world!", Req).


OR


Req2 = cowboy_req:reply(200, [
    {<<"content-type">>, <<"text/plain">>}
], "Hello world!", Req).
