To-do app works locally, not on Heroku

Hello,

The to-do app from the tutorial section (https://blockstack.org/tutorials/todo-list) works great when I run my local server. However, when I deploy it to Heroku, I get a “Sign In Request
Invalid Sign In Request” message every time I try to sign in.

How can I fix this? Thanks for your help!

Hey @TheSchnaz
Are there any CORS-related errors in the dev console? (in the Blockstack browser)

Hello, is there a tutorial on how to deploy to heroku?
I went through the steps on gaia github to deploy heroku, after that, how do I set my blockstack browser to connect to the new heroku app?
Thanks!
