I thought I had this Ktor networking with an MVP architecture working on iOS, but now I’m getting the following exception when trying to dispatch the result on Dispatchers.Main.

Anyone else running into an error like this?

[Tijl]

you need to upgrade to version

1.3.9-native-mt-2

of

org.jetbrains.kotlinx:kotlinx-coroutines-core

[Evan]

@Tijl thank you so much, that got things working again!

Getting the same exception with coroutines 1.3.9-native-mt-2 and ktor 1.4.1. @Tijl @Evan any ideas? 🤔

[Tijl]

make sure you are actually using coroutines 1.3.9-native-mt-2 and it’s not upgraded by some other dependency, you can do this (usually) by adding !! in the declaration

[nrobi]

hmm, well I’m using isForce, since I had some issue s with strictly 🤔

[nrobi]

implementation(Dependencies.Common.coroutine.Core) {
    isForce = true
}

[Tijl]

this exact bug (waitAll not working), was fixed in that version, so then I’d double check your dependency graph. Are you sure you have the exact same cause as the exception? if it’s something else I’d open a new thread.

I’m not sure it’s related to awaitAll().

Fatal exception in coroutines machinery for DispatchedContinuation[MainDispatcher

Tried using both the Dispatchers.Main, and a custom one with the dispatch_async(dispatch_get_main_queue()) implementation 🤔

[Tijl]

if you look at the stacktrace in this thread, it’s clearly awaitAll that is the cause, which was fixed in the version I pointed out, which is why it fixed the problem. if you don’t have awaitAll in your stacktrace, you have a different problem.

[nrobi]

You’re right, diving deeper in the stacktrace helped, looks like it’s the same as https://youtrack.jetbrains.com/issue/KTOR-1087
