Hey,

I deployed my app with Heroku. When I install the app first time it crashes and throws an error “Invalid OAuth callback” but after 3 to 4 tries it’s working fine. I’ve been stuck on this error, Please help me.

Hi,
This can be an issue due to config variable, try put them static, it will work then.
