I'm trying to implement TikTok login kit into my app.
I'm following this guide https://developers.tiktok.com/doc/login-kit-web and i'm stuck on point 2.1 because after succesfully login the user, and succesfully grant app permissions from the user i'm beeing redirect to this url : https://open-api.tiktok.com/platform/oauth/undefined
I'm pretty sure my url is correct because if i insert in it some errors on purpose i get an error page .. like wrong client key, wrong response type, scope, redirect url ecc..
Anyone knows what am i doing wrong?
thanks!
