why i can't enable minify because of kotlinx serialization? i have also added serialization related rules in proguard. Does anyone know any latest solution?

I used kotlin serialisation with minification just fine

did you added anything in proguard file?

We did annotation to all fields in classes that are involved in the serialisation

I have done it but not working. Ktor client response parsing failed because of minification

What class/field is it missing? Check the mapping file to see what is done with that class/field. Check the proguard configuration that it covers that class/field.

Okay
