Errors in production attempting to hit localhost

[jollygreenegiant]

I'm getting the following error in production:

HTTP request to http://localhost (POST) failed with message: Job was cancelled

io.github.jan.supabase.network.KtorSupabaseHttpClient.request (KtorSupabaseHttpClient.kt:55)

io.github.jan.supabase.network.KtorSupabaseHttpClient$request$1.invokeSuspend (KtorSupabaseHttpClient.kt:12)

It seems to be happening to users intermittently - some have reported it happens all the time, some say they've been able to restart or reinstall the app and that seems to fix it, and I haven't been able to track down a cause.

It seems odd to me that the error includes localhost - I don't think I have a reference to that anywhere in my app and it should never be hitting anything but the remote server.

Any ideas what might be causing this?

How do you call Supabase functions? This looks like the coroutine scope you are calling the functions from was cancelled. I think Ktor tries to reach localhost in case of some failure.

[jollygreenegiant]

The full URL call is this:

http://localhost?user_id=eq.<user_id>&reading_status=eq.CURRENTLY_READING&order=start_date.desc.nullslast&select=%2A (GET)

Being called from a ViewModel like this:

// In HomeViewModel
viewModelScope.coroutineScope.launch {
    userBooksRepository.getCurrentBooks(authRepository.requireUserId())
}

// In UserBooksRepository
suspend fun getCurrentBooks(forUserId: String) {
    val books = supabaseClient.postgrest.from("user_books_with_stats")
            .select {
                filter {
                    eq("user_id", forUserId)
                    eq("reading_status", "CURRENTLY_READING")
                }
                order("start_date", Order.DESCENDING)
            }.decodeList<UserBookWithStats>()
    }
        
    currentBooksFlow.emit(books)
}

The viewModelScope is probably just the normal Android ViewModel Scope right? Also can you post the full stacktrace?

[jollygreenegiant]

It's using KMMViewModel, but it's based on the default Android ViewModel, yes.

Full trace:

I think there we have the problem:

androidx.lifecycle.ViewModel.closeWithRuntimeException (ViewModel.kt:252)
androidx.lifecycle.ViewModel.clear (ViewModel.java:189)
androidx.lifecycle.ViewModelStore.clear (ViewModelStore.kt:69)
androidx.navigation.NavControllerViewModel.clear (NavControllerViewModel.kt:33)

androidx.navigation.NavController.unlinkChildFromParent$navigation_runtime_release (NavController.kt:163)

androidx.navigation.compose.ComposeNavigator.onTransitionComplete (ComposeNavigator.kt:82)
androidx.navigation.compose.NavHostKt$NavHost$15.invokeSuspend (NavHost.kt:314)

It looks like the ViewModel "clear" method is called, which means the viewModelScope gets cancelled. And that means all further requests will fail

I'm not sure why that happens without looking at your full code. Maybe its a KMMViewmodel thing
