I’m having an issue with parsing proguard minified with jackson. This is the error I’m getting:

com.fasterxml.jackson.databind.exc.InvalidDefinitionException: Cannot construct instance of `fi.millisecond.canvas.flow.data.models.b.d` (no Creators, like default construct, exist): cannot deserialize from Object value (no delegate- or property-based Creator)

The class that’s referenced here looks like this:

data class ConfigResponse(val appConfig: AppConfigPrimitive)

Without proguard it’s working perfectly, but with it I have this exception

The rules I’m using right now (after hours of googling and adding different ones) are these:

-keep class com.fasterxml.jackson.databind.ObjectMapper {
    public <methods>;
    protected <methods>;
}
-keep class com.fasterxml.jackson.databind.ObjectWriter {
    public ** writeValueAsString(**);
}
-keepnames class com.fasterxml.jackson.** { *; }
-dontwarn com.fasterxml.jackson.databind.**

-keep,allowobfuscation @interface kotlin.Metadata
-keepclassmembers @kotlin.Metadata class * {
    <methods>;
}
-keep class kotlin.reflect.** { *; }

-keepclassmembers,allowoptimization enum * {
    public static **[] values();
    public static ** valueOf(java.lang.String);
    **[] $VALUES;
    public *;
}

If anybody is interested in helping me solve this issue it would be really nice. I can also post my proguard logs if you want.
