While trying to use FacebookSDK in an iOS app, I get this message:
FBSDKLog: Error for request to endpoint ‘123654789?fields=name,supports_attribution,supports_implicit_sdk_logging,gdpv4_nux_enabled,gdpv4_nux_content': An open FBSession must be specified for calls to this endpoint
Why exactly do I get this?
I took the code from HelloFacebookSample
provided with the FacebookSDK and put it into my app, but I must have missed some critical part.
