How to call an endpoint anonymously

[OnlyOneBDS]

Hi all,

I'm currently trying to add a dropdown list in the registration page that is to be populated by a method that calls an endpoint. When I do, I get an unauthorized error message when I check the dev console. After reading some threads on here, I went back and created a new endpoint that does the same thing but instead added AllowAnonymous to it. After running it again, this time I do get something back but I get redirected back to the login page. How do I fix this?

Thanks in advance
