I have Scala (Silhouette + Play) backend app and frontend app written in react.
http://localhost:9000/authenticate/google sends request to facebook. Facebook "does" something, and redirects to my front-end app with token in the link.
There is a part of my implementation: result <- authenticatorService.embed(value, Redirect(s"http://localhost:3000?user-id=${user}"))
Then I am redirecting to: http://localhost:3000/?user-id=Rep(Apply%20Function%20user)#_=_.
The part afteruser-id?= should be token, but it's name of function.
I think there's a mistake in configuration on facebook site.
Does someone used this API in Scala projects?
