Silverstripe Admin: Redirect is not allowed for preflight request

[ghost]

Hi!

I'm trying to migrate legacy api calls in the old sliverstripe-instagram module to just use your own instagram module for calls. However, when I try to make the call from the admin, I always get the above error from the console. I've checked and double checked my addressed in both the in-code callback, and on the actual facebook developers page. have you encountered this issue before? Any info you might have would be really appreciated. Thanks!
