I'm using the session reciep with an express backend. Should I set location.origin as the apiDomain, when initializing the frontend, or the apiDomain of the hosted supertokens service? When putting in the apiDomain of the hosted supertokens service, I get CORS errors. When putting in location.origin, the backend logic works fine, but doesSessionExist() always resolves to false and refreshing the accessToken also doesn't work.

Hey. You need to set it to your express backend address

Alright, so in my case this would be location.origin. How can I debug why the refreshing fails?

Enable backend debug logs and see the logs when calling the refresh api

Ah alright, looked for an option in the init() args. Found the

DEBUG=com.supertokens

way of doing it, thanks!
