Hey, we at Scoutflo are integrating supertokens and there are few issues are facing 1) Unable to send our custom fields like first_name and last_name. When we send that in normal signup, it is returning 400. But when we send only email and password it works. Also, when we update the info of the user their first_name and last_name are getting stored. 2) Login through GitHub is not storing first_name and last_name values.,
