Hey eveyone, I'm getting a runtime exception with the following cause when run with proguard.

Do I need to specify a keep rule for each empty constructor?

Android studio 3.2,
Kotlin 1.2.71
Koin 1.0.0

Caused by: org.koin.d.a: Can't create definition for 'Single [name='a',class='com.package.b.a']' due to error :
    		No constructor found for class 'class com.package.b.a'
