Polymorphic serializer Error

[hmshohrab]

When I use "minifyEnabled true" that error message is thrown...

kotlinx.serialization.json.internal.JsonDecodingException: Polymorphic serializer was not found for missing class discriminator ('null') JSON input: {"success":true,"message":"Otp sent successfully","data":{"countryCode":"880","mobileNo":" 99999999","type":"New","testOtp":63401}}

how can i fix it?

If you're using a Call like fun fetchSomething(): Call<Something>, make sure it's not a suspend function
