Runtime error when trying to restore is causing items to be "missing"

Amazon IAP
#1

I’ve tried making a few test purchases of non-consumable items, and then removing+reinstalling the app. When I call store.restore to get the purchased items back, I am seeing this error:

06-09 15:19:47.939: E/AmazonCorona(18490): Unknown exception: ?:0: attempt to index field '?' (a nil value) 06-09 15:19:47.939: W/System.err(18490): com.naef.jnlua.LuaRuntimeException: ?:0: attempt to index field '?'

What seems to be happening is that if I have say 4 non-consumable items, one of them will be restored, this error will appear and the remaining 3 will not be restored.  

If I then kill the app and try again, I might get another one of the items restored first (as they don’t seem to be restored in any particular order), but it’s not a good user experience to have to keep killing the app to try and restore purchases.  

Any idea what the error could be? It appears to originate in the plugin itself:

LuaBridge.purchaseCallBack(LuaBridge.java:347)

Please ignore this - the error was being called because my code was calling the restore function before calling loadProducts, which caused issues in my callback function. 

The attempt to index field was an exception in my lua code, when I saw the error message it seemed to point to the plugin code which threw me.
