I’m having a similar issue. We have an existing manual implementation for handling in-app purchases. We integrated RevenueCat in observer mode with the intention of sending events straight to Mixpanel. The app occasionally crashes at launch, and also occasionally when making a purchase. On 3.2.2 via cocoapods.

Error is - Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '*** -[__NSPlaceholderDictionary initWithObjects:forKeys:count:]: attempt to insert nil object from objects[1]'

Logs leading up to the crash. This is when I actively make a purchase on the device:

@aboedo does this seem related?
