Registration and Login Not working on Amazonia (next js, sanity.io) Project

Hey I’m having trouble with the implementation of this code, I am able to add products and set them their different categories, so far have managed to implement everything well with the youtube tutorial, but for some reason I’m not able to register user’s or login via the front-end but my Users can added in the sanity platform which is kinda weird I’m wondering where I went wrong as it does not show any errors except printing out that user does not exist

your help will be much appreciated
