Invalid credentials when trying to authenticate via Facebook

Question

Can't connect via facebook anymore on my rails app

Here is the error I get

GET https://www.myapp.com/auth/failure?message=invalid_credentials&strategy=facebook 404

No changes were made to the app and it worked fine 2 days ago

Answer 1

Same question is asked here:

Omniauth: callback not firing, returns failure with "invalid credentials"

bundle update omniauth
bundle update omniauth-facebook

solves the issue.
