Unable to extract error_description from OauthCallbackError using auth0 provider

[jacobmaizel]

I am doing access control based on certain user metadata within auth0 flows. When the auth0 login fails due to these access control restrictions, I am supplying a specific error message. When debug is enabled, I can clearly see the error description I am looking for is contained within the OAuthCallbackError that is thrown.

Is there any way I can pass this data as a query parameter to my custom error page?

Currently on the custom error page, auth js just sends a generic "?error=OauthCallbackError" which does not help as it is so generic.
