Self-service registration Not working in my angular application

Hello there,

I have a problem in the self-service registration. When i click on “Sign-Up” link i get a blank form that is supposed to be the registration form, and i get the following server error in the console 501 “Unsupported operation”.

I’ve followed all the steps in different Okta documentations but still getting the same error. Can you help me with this PLEASE !

Under Security → Profile Enrollment, please ensure that you have a Profile Enrollment Policy created that is assigned to your application and has Self-service registration set to Allowed.

Yes i did allow the Self-service registration but still not working. i don’t know why
