Hi, I recently get these exceptions (using coroutines and okhttp):

E/AndroidRuntime: FATAL EXCEPTION: DefaultDispatcher-worker-1
    Process: io.github.kartoffelsup.nuntius, PID: 2334
    java.lang.NoSuchMethodError: No static method post$default(Lio/github/kartoffelsup/nuntius/client/NuntiusApiService;Ljava/lang/String;Ljava/lang/Object;Lkotlinx/serialization/KSerializer;Lkotlinx/serialization/KSerializer;Ljava/lang/String;ILjava/lang/Object;Lkotlin/coroutines/Continuation;)Ljava/lang/Object; in class Lio/github/kartoffelsup/nuntius/client/NuntiusApiService; or its super classes (declaration of 'io.github.kartoffelsup.nuntius.client.NuntiusApiService' appears in /data/app/io.github.kartoffelsup.nuntius-1/base.apk:classes3.dex)

I'm guessing I need a proguard rule or something? I added this:

-keepclassmembers class io.github.kartoffelsup.nuntius.client.NuntiusApiService {
    *;
}

but that didn't help unfortunately. Code is here:
https://github.com/kartoffelsup/nuntius-app/blob/master/app/src/main/java/io/github/kartoffelsup/nuntius/ui/user/UserLoginScreen.kt#L94
https://github.com/kartoffelsup/nuntius/blob/master/client/src/commonMain/kotlin/io/github/kartoffelsup/nuntius/client/NuntiusApiService.kt#L11-L17
Any pointers? Thanks!

The method is definitely in the jar:

javap NuntiusApiService.class
Compiled from "NuntiusApiService.kt"
public final class io.github.kartoffelsup.nuntius.client.NuntiusApiService {
  public final <A, B> java.lang.Object post(java.lang.String, A, kotlinx.serialization.KSerializer<A>, kotlinx.serialization.KSerializer<B>, java.lang.String, kotlin.coroutines.Continuation<? super io.github.kartoffelsup.nuntius.client.ApiResult>);
  public static java.lang.Object post$default(io.github.kartoffelsup.nuntius.client.NuntiusApiService, java.lang.String, java.lang.Object, kotlinx.serialization.KSerializer, kotlinx.serialization.KSerializer, java.lang.String, kotlin.coroutines.Continuation, int, java.lang.Object);
  public final <B> java.lang.Object get(java.lang.String, kotlinx.serialization.KSerializer<B>, java.lang.String, kotlin.coroutines.Continuation<? super io.github.kartoffelsup.nuntius.client.ApiResult>);
  public static java.lang.Object get$default(io.github.kartoffelsup.nuntius.client.NuntiusApiService, java.lang.String, kotlinx.serialization.KSerializer, java.lang.String, kotlin.coroutines.Continuation, int, java.lang.Object);
  final <A, B> java.lang.Object request(java.lang.String, io.github.kartoffelsup.nuntius.client.NuntiusHttpMethod, A, kotlinx.serialization.KSerializer<A>, kotlinx.serialization.KSerializer<B>, java.lang.String, kotlin.coroutines.Continuation<? super io.github.kartoffelsup.nuntius.client.ApiResult>);
  static java.lang.Object request$default(io.github.kartoffelsup.nuntius.client.NuntiusApiService, java.lang.String, io.github.kartoffelsup.nuntius.client.NuntiusHttpMethod, java.lang.Object, kotlinx.serialization.KSerializer, kotlinx.serialization.KSerializer, java.lang.String, kotlin.coroutines.Continuation, int, java.lang.Object);
  public io.github.kartoffelsup.nuntius.client.NuntiusApiService(io.github.kartoffelsup.nuntius.client.NuntiusHttpClient, kotlinx.serialization.json.Json);
}

and I set:

minifyEnabled false
            shrinkResources false

what else could cause this? :<
