TargetException: Non-static method requires a target

[jacquesleemans]

Causes a fatal crash on Android (multiple devices and OS)

• Unity Version: 6000.0.46f1
• Facebook SDK:
• Unity IAP Version: 5.0.1

Manifest:

    <meta-data android:name="com.facebook.sdk.AutoLogAppEventsEnabled" android:value="false" />

I also disabled all automatic events in Facebook Developer and Facebook Event Manager

In code I also set SetAutoLogAppEventsEnabled to false:

FB.Mobile.SetAutoLogAppEventsEnabled(false);

Debugging IsImplicitPurchaseLoggingEnabled() returns false

var isImplicitPurchaseLoggingEnabled = FB.Mobile.IsImplicitPurchaseLoggingEnabled();

TargetException: Non-static method requires a target.

Using Rider to Decompile CodelessIAPAutoLog, it doesnt seem like addListenerToIAPButtons handles IsImplicitPurchaseLoggingEnabled:

internal static void addListenerToIAPButtons(object listenerObject)
  {
    UnityEngine.Object[] objectsOfTypeByName = CodelessIAPAutoLog.FindObjectsOfTypeByName("IAPButton", "UnityEngine.Purchasing");
    if (objectsOfTypeByName == null)
      return;
    foreach (UnityEngine.Object gameObject in objectsOfTypeByName)
      CodelessIAPAutoLog.addListenerToGameObject(gameObject, listenerObject);
  }

For example, maybe this would solve it:

internal static void addListenerToIAPButtons(object listenerObject)
  {
//Suggestion
if (!FB.Mobile.IsImplicitPurchaseLoggingEnabled())
        return;

    UnityEngine.Object[] objectsOfTypeByName = CodelessIAPAutoLog.FindObjectsOfTypeByName("IAPButton", "UnityEngine.Purchasing");
    if (objectsOfTypeByName == null)
      return;
    foreach (UnityEngine.Object gameObject in objectsOfTypeByName)
      CodelessIAPAutoLog.addListenerToGameObject(gameObject, listenerObject);
  }

Expected behaviour:
When FB.Mobile.IsImplicitPurchaseLoggingEnabled() returns false, addListenerToIAPButtons should not execute
