Entering this in the console:

        Raven.config('https://<key>@sentry.io/<key>').install()
        try{
          throw new Error('test');
        } catch(err){
          console.log('err', err);
          Raven.captureException(err);
        }

returns:

(with the reponse message being Event dropped due to filter)

Versions:

• “raven”: “2.2.1”,
• “raven-js”: “^3.19.1”,

I had initially reported it here
