Add any other context about the problem here.

As far as I can tell, this crash wasn't happening on the previous 6.1.1 SDK version, except for some extremely rare occurrences here and there

Hi @matteinn,

Looking at the stack trace, it seems to be crashing when we try to fetch offerings after SDK configuration from your hint... A few things that would be useful:

• Do you have any logs from your crash monitoring tool?
• Could you provide a snippet of the code you use to configure the SDK?
• Also, do you call getOfferings near app startup? If so, could we get a snippet of that code as well?
• Could you double-check you're not configuring the SDK multiple times in any path?

Let us know if you notice anything else in the meantime about these crashes!

Nope

• Could you provide a snippet of the code you use to configure the SDK?

At app opening...

Purchases.logLevel = if (BuildConfig.DEBUG) LogLevel.VERBOSE else LogLevel.ERROR

val configuration = PurchasesConfiguration.Builder(context, REDACTED)
    .appUserID(appUserId)
    .build()

Purchases.configure(configuration).apply {
    updatedCustomerInfoListener = this@PurchasesManager
}

with(Purchases.sharedInstance) {
    setEmail(email)
    ...
    collectDeviceIdentifiers()
}

userRepository.isLoggedIn
    .subscribe({ isLoggedIn ->
                when (isLoggedIn) {
                    true -> { purchases.logInWith(...) }
                    false -> { purchases.logOut() }
                }
    }, {})
    .also{ disposables.add(it) }

• Also, do you call getOfferings near app startup? If so, could we get a snippet of that code as well?

Nope, only when strictly needed (e.g. when a paywall needs to be shown)

---

• Could you double-check you're not configuring the SDK multiple times in any path?

Yes, that's not happening

Let us know if you notice anything else in the meantime about these crashes!

Absolutely!
