I cloned the following Polymer todo-list app from https://github.com/PolymerLabs/todo-list and after setting it up as per the instructions, i got it running on local with gulp serve. I could signin and add/delete/update todos as expected. However, a colleague of mine who did the same thing is getting the following error
My colleague is working from the Philippines if that matters at all. Could someone please advise how I can get it working on his local machine? We're both using Chrome btw and he does not run into any issues using a version that was deployed to firebase, just encountering the error on localhost. Thanks.
