Hi

My app is crashing when clicking on in-app purchases.

My app consists of two targets where I have created two bundle ID and enabled in-app purchases for both.

Any clues?

The log has the following content:

"'NSRangeException', reason: '*** -[__NSArrayM objectAtIndex:]: index 18446744073709551615 beyond bounds for empty array'...... -[MKStoreManager addToQueue:]...[MKStoreManager buyFeature:onComplete:onCancelled:].....[MKSKProduct verifyProductForReviewAccess:onComplete:onError:]....[MKStoreManager buyFeature:onComplete:onCancelled:] .......-[DBPurchaseManager makePurchase:onComplete:onCancel:] ..... -[vShopCoinsPopup clickCoinsPack1:]"

That means somewhere in the method "addToQueue" which was called by "buyFeature" etc. you refrenced a mutable array's objectAtIndex:184467440737.. but the array had no objects in it. This error is usually something like "objectAtIndex:-1" where the index is interpreted as an unsigned integer. You need to figure out why this happened.

One possible cause of this problem is that your productsResponse returned an empty array of response.products and you went ahead with a purchase anyway.
