NativeScript there was an error processing the sign in

I am using auth0- lock and trying to get to sign in page. I am unable to sign in as i get only the generic message shown above.

I checked the logs, It is not logged in there either. Can u please help us in understanding the issue better?

That’s not enough information; using Lock in a centralized login approach (aka hosted login page) or Lock embedded in the client application? If embedded, NativeScript is for native application so although it uses traditional web frameworks it’s still a mobile application so Lock Web is most likely unsuitable. If centralized, which version of Lock? What do you get in dashboard logs? What do you get by analyzing the HTTP communications?
