@joeogun, I guess this thread is for similar thread before:

SAML Mapbox error- make sure our application username format for Mapbox is an email address

I’m having a problem setting up Mapbox Single sign-on. I have added the IdP sign-on URL which is the SAML Protocol URL and the Issuer ID which is shown in the SAML usage tab. My issue is that when I go to test it in Mapbox I get an issue which says " Your username does not appear to be in the form of an email address, please contact your IT admin and let them know your “subject name id” is malformed. " How do I make my username in a form on an email address in Auth0?
