Hello everyone, I have a problem while using this ...

Hello everyone, I have a problem while using this module combined with Ktor. I keep getting
InvalidDefinitionException - (no Creators, like default construct, exist): cannot deserialize from Object value (no delegate- or property-based Creator)
I'm installing the feature as follows:
Copy code
install(ContentNegotiation) {
            jackson {

                // Set how the dates should be handled
                dateFormat = SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss.SSS'Z'").apply {
                    timeZone = TimeZone.getTimeZone("UTC")
                }

                // Do not serialize null values
                setSerializationInclusion(JsonInclude.Include.NON_NULL)

                // Do not worry about unknown properties, ignoring them
                configure(DeserializationFeature.FAIL_ON_UNKNOWN_PROPERTIES, false)

                // If we receive an empty object, treat it as null
                enable(DeserializationFeature.ACCEPT_EMPTY_STRING_AS_NULL_OBJECT)

                //accept also lowercase value in enum fields
                enable(MapperFeature.ACCEPT_CASE_INSENSITIVE_ENUMS)
            }
        }
Every time I do something like
call.receive<MyClass>()
I get that error. I really don't know what to do
