I’ve seen this message from @guy1812 Pre registration hook set non-metadata user info? - #25 by guy1812, is it a real bug or not? @dan.woda or @James.Morrison any update on this? Because unfortunately we’ve reproduced it past friday.
Anyway I can explain what we want to achieve so far and maybe you can suggest us to do it another way or with a workaround the way we want to do it?
We want to send a request to some of our backends whith the generated auth0 user id on passwordless registration in order to return our external user identifier and get it stored into auth0 user profile, in order to have it embedded into the JWT id token. Thus when we do requests thereafter on our own api whith this JWT id token it will embed both auth0 id and our external user id which is the one we care of.
