After I have successfully paid for the subscription item, I subscribe to the same subscription item again, Google prompts you to subscribe to the same item Dialog, when the Dialog dismiss, it will 100% crash.

lib version:2.2.0

Cause of the problem:
The purchase info for the non-subscribed item is obtained here, so null is returned
