Thank you for your response! I’m not sure how to structure it to return what I need in that case - we’ve tried appending it to the user’s metadata values, but to pass that through it needs to be appended to the id_token anyway as far as I can tell so it runs into the same issue. Is there an accepted way to return large values from Auth0 to a SPA using popup mode? Somewhere I could store it while inside a rule, that I can then access later?
Weirdly, having the audience value in the incorrect place results in returning an access_token instead of an id_token, but then runs into these errors.
