[iOS][Debug] Buying a sub or an IAP makes the app crash

[PierreCapo]

On iOS, in debug mode, around 3 times out of 4 after buying a Subscription or an IAP this problem happens. After the iOS native modal to pay is shown and I pay with an Apple test account, my app crashes (it freezes on the Purchasely paywall)

Those are the Xcode logs I get:

*** Assertion failure in -[RCTEventEmitter sendEventWithName:body:](), /Users/xxxxxx/Documents/xxxxxx/node_modules/react-native/React/Modules/RCTEventEmitter.m:53
*** Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'Error when sending event: PURCHASE_LISTENER with body: (null). RCTCallableJSModules is not set. This is probably because you've explicitly synthesized the RCTCallableJSModules in PurchaselyRN, even though it's inherited from RCTEventEmitter.'
*** First throw call stack:

Environment Details
I always develop on a real device, so this bug happens on a real device, but could also happen on simulators I guess.
It can happen on various different iPhone models.
The app uses Purchasely v4.5.3 but this problem has been here for months, so it's not a recent regression.

Same issue here, using v5.0.2. Any updates ?

Hello @PierreCapo @hcourthias

Apologies for the late answer, we do not track actively issues here.
I suggest to use our support center from Purchasely console for dedicated support.

Are you using Purchasely.addPurchasedListener()? The crash seems to originate from there, but I am unable to reproduce it.
Are you using that method and able to reproduce the crash consistently under any circumstances after a purchase?

Hello @kherembourg,

I will use the support center next time! On our side, we are not using Purchasely.addPurchasedListener() but only Purchasely.setPaywallActionInterceptorCallback(). We are also using storekit 2 now. I am not able to reproduce the crash consistently.

Thanks for your reply @hcourthias

Then it probably means that the purchase listener is triggered too early in some cases when the application starts and StoreKit queue is being processed.
We are going to make some changes to avoid this in the next version.

Thanks @kherembourg !
Same as @hcourthias , we are not using Purchasely.addPurchasedListener().

Hello @PierreCapo @hcourthias

We think we found the reason of this crash, we forgot to add an instruction for the Purchase Listener.
We still don't know why we are not able to replicate at all but version 5.0.6 released today should fix your issue.

Thank you very much for your report!
