[Solved] Weird Add Product Error

After updating to the newest IAP we are starting to see an issue with initializing IAP.

When we build for Gameroom it fails at StandardPurchasingModule.Instance() with the following print out:

UnityIAP FB: Facebook already Initialized, checking...
UnityIAP FB: Init OK
UnityIAP FB: AppId [ID]
UnityIAP FB: already logged in
UnityIAP FB: token UserId [ID]
UnityIAP FB: token ExpirationTime 8/28/2017 4:31:05 PM

We thought we would give just a regular standalone build a try and it got past StandardPurchasingModule.Instance() and was able to print out one of the Products ID set:

Adding Product : default1
|MacAppStore -> default1
|MoolahAppStore -> default1
|SamsungApps -> default1
|WinRT -> default1
|TizenStore -> default1
|AppleAppStore -> default1
|GooglePlay -> default1
|AmazonApps -> default1
|FacebookStore -> default1

But then it fails when trying to add the Ids to the builder:

Argument cannot be null.
Parameter name: key

Any Ideas what could be the issue?

 

Update with testing on an empty project:

Facebook 7.10.0
Unity IAP 1.11.4

If Facebook Initializes first the above error will show, yet if UnityIAP initalizes facebook i recieve the following output:

UnityIAP FB: AuthCallback()
UnityIAP FB: token UserId [ID]
UnityIAP FB: token ExpirationTime [Still Valid]
UnityIAP FB: productRequest = /[AppId]/products
UnityIAP FB: ProductListCallback() RawResult had an empty "data[]"
Billing failed to initialize!

So when I started to Initialize facebook first I tried calling the following:

FB.API("/[AppId]/products", HttpMethod.GET, (t) => Debug.Log(t.RawResult));

This returned all the purchases I set up in the facebook console, not an empty data[].

Is Unity IAP not calling FB.API?

 

I am also having this problem. Can you tell me when this problem will be resolved?
There is not much time left for the game being developed.
