Since Friday, March 11 it is impossible to authorize with Uber.
Once user is prompted to Approve (Accept) Application permissions uber response with the following error (redirects to URL with following params):
callback?error=invalid_request&error_description=Duplicate+redirect_uri+parameter.
Although if Uber Account is already connected with Application user can successfully log in.
I'm using nodejs, express, passport, UberStrategy, which uses passport-oauth2. We've been using Uber API for last 5 months and never had this issue before and none of these libs were updated on our side.
