With custom databases the get create and login trigger simultaneously

Hi there, I am using a custom database, now wanted to trigger create operation only through my form. I have successfully set up the form now when I trigger the create operation from my form, It will trigger the get, create, and login operation in the auth0. This is creating a problem though I am able to create a user in my external database on the auth0 side it shows the wrong username and password as it is trigger login script as well. Need help to remove though issues
