        },function(resposta){
                console.log(resposta) 
         });

Answer 1

From what I’ve researched, this could be caused by something that’s intercepting your request, and sending an empty request.

Possibly a ad blocker (like Adblock), as indicated in this SOEN response:

Suggestion: tries to install the Fiddler to see how the request is getting done, because there must be something intercepting the request... after doing this, try to check in other browsers, and see how the requests are in each of the browsers... so you can isolate the problem more and more.

EDIT More suggestions based on SOEN:

• Start the Chrome with --disable-extensions at the command line (https://stackoverflow.com/a/21400449/195417)

• Check that the request is not being made to another domain

• Resource is being loaded from browser cache (https://stackoverflow.com/a/21272049/195417)... e.g. for lack of server connectivity, the browser takes a cache resource, without currently doing the request.

Answer 2

Obs: There’s a question that’s extremely similar to yours here, the image is identical.

Translated Response from SOEN

The feature could be being blocked by an extension (Adblock, etc..)

The message is there because the request to redeem this feature has never been made, so the headers being presented are not real.
