Why is it asking me for firehose permissions


I am trying to make a simple query into streaming api through the apogee web console: https://dev.twitter.com/console
Here is a snapshot of the result i get:

It keeps giving me 401 unauthorised error, when that can’t be because I’ve authorised apigee to use my credentials for the Oauth.
(and timestamp shouldn’t be a problem because its a web console AND my local clock is set automatically)

What bothers me is that it says:
WWW-Authenticate: OAuth realm=“Firehose”

why? and can anybody think of any way to fix this?

Thank you so much.
