so I have this piece of code:

if (marketingConsentTypes != null && marketingConsentTypes.all { it in validEnumValues }) {
    viewModelScope.launch(coroutineDispatchers.main) {
        marketingConsentTypes.forEach { consentType ->
            giveConsent.execute(
                GiveConsent.Input(
                    consentType = GiveConsent.ConsentType.valueOf(consentType),
                    hasGivenConsent = true
                )
            ).await()
        }

        isLoading.postValue(false)
    }
} else {
    error.postValue(Event(Throwable()))
}

the issue is not that I am running this usecase in a loop, that’s what I want

the issue is that I would like to get back the Throwable that this usecase already does return for me, with Rx usually I’d get it back in the error block of the subscribe, here where can I get it to let my mutable property know that the error happened?

oh I can just…doOnError instead of await() immediately…

why not use
https://kotlinlang.org/api/kotlinx.coroutines/kotlinx-coroutines-core/kotlinx.coroutines/suspend-cancellable-coroutine.html

[oday]

yes I’m looking at that

[oday]

I am not sure how to go from what i have to the above

[oday]

viewModelScope.launch(coroutineDispatchers.main) {
    suspendCancellableCoroutine<GiveConsent.ConsentType> {
        marketingConsentTypes.forEach { consentType ->

            giveConsent.execute(
                GiveConsent.Input(
                    consentType = GiveConsent.ConsentType.valueOf(consentType),
                    hasGivenConsent = true
                )
            ).doOnError {
                cancel("Message", Throwable("Exception thrown"))
            }
        }
        
        isLoading.postValue(false)

        addSuccessComponents()
    }
}
