[Solved] Unity IAP For FaceBook

Unity Services
1

IAP Ver: 1.14.1
FB Ver : 7.10.1
Client: GameRoom

If I call Facebook.Unity.FB.LogInWithReadPermissions function, then init IAP，will cause this error.
If I call init IAP directly, iap everything works fine。

Error Log:

@melefans Can you describe the problem a bit more, as calling IAP initialize directly seems to work fine for you?

Unity IAP will attempt to login with appropriate permissions if it detects that the user isn’t already logged-in. If you’re seeing an error after explicitly logging in then there may be a permission issue – what’s in your permissions list? Are you testing this on WebGL or Windows?

thank you for your reply。
Yes, if I do not login facebook, Iap is working。

@JayR @JeffDUnity3D
I have solved my issue because I initialized Iap twice。
Thank you:)
