[Solved] Facebook Gameroom IAP - Null ref RetrieveProducts

Unity Services
1

It seems that if I call FB.Init() and FB.LogWithPermission before initializing the store, when I am initializing the store, I get this error:

UnityIAP FB: Facebook already Initialized, checking…
UnityIAP FB: Init OK
UnityIAP FB: AppId 1603407643081173
UnityIAP FB: already logged in

which I don’t have if I don’t call FB.Init() and FB.LogWithPermission before. Though I need the user Facebook ID before I initialize the store.

Thanks,

@esg-timothee

We have identified an initialization issue with the Facebook part of our plugin. We have a fix and it should be ready by the next version of the IAP plugin. (You should get an update notification in the Editor when this version is available.) The plugin is in QA right now and should be available very soon.

I apologize for any inconvenience this has caused.

Version 1.12.0 is now available and it should have the fix for Facebook that I mentioned.

If you still have issues with that version, please let us know.
