# ktor

[Aleksandr Ivanov]

Trying to migrate from ktor 1.5.3 to 1.6.0 in my multiplatform project, but got a freeze exception, when initialise HttpClient. I found that there is already known issue with HashMaps (https://github.com/Kotlin/kotlinx.serialization/issues/1450) but looks like it is not my case.

There is my stack trace:

Uncaught Kotlin exception: kotlin.native.concurrent.InvalidMutabilityException: mutation attempt of frozen kotlinx.coroutines.JobImpl@2516528

My version changes:
kotlin: 1.4.32 -> 1.5.10
Ktor: 1.5.3 -> 1.6.0
kotlinx.coroutines: 1.4.3-native-mt -> 1.5.0-native-mt
kotlinx.serialization: 1.1.0 -> 1.2.1

Does somebody faced this issue?

[Aleksei Tirman [JB]]

Could you please file an issue in YouTrack https://youtrack.jetbrains.com/newIssue?project=KTOR with a sample code for reproduction attached?

[Aleksandr Ivanov]

Yes, At this moment I’m trying to reproduce issue in demo project.

[Aleksandr Ivanov]

It looks like I found the reason. It is because of apollo library included in project. When I removed apollo from project the problem is gone.

[Aleksandr Ivanov]

@mbonnin Hi, Does apollo graphql library includes coroutines? If so which version?

[mbonnin]

Yes it does. The specific version depends the apollo-android version but it's not the native-mt one

[mbonnin]

You can get it with ./gradlew dependencies , that should show all the transitives dependencies and how they are resolved

[mbonnin]

Maybe you need to force coroutines-mt ? https://www.apollographql.com/docs/android/essentials/get-started-multiplatform/#multithreaded-coroutines

[Aleksandr Ivanov]

Let me try, thank you

[Aleksandr Ivanov]

Yes, it helps. 🎉 Thanks again.
