IAP 3 Error refreshing inventory (querying prices of items). (response: 5:Developer Error)

When we call loadProducts for Google IAP v3 we’re getting this error back: “Error refreshing inventory (querying prices of items). (response: 5:Developer Error)”

Any ideas why? It’s the first time we’ve used IAP in this particular product, but we use it heavily in other products and the product list always returns the right items.

So this turned out to be our issue - we were passing null as the productID of one of our IAP.
