How does one post an object via

HttpClient

that should be Json Encoded? Using iOS, if that matters, and I have the

JsonFeature

installed... but I get

kotlin.ClassCastException: example.model.Person cannot be cast to io.ktor.client.call.HttpClientCall

. Here's my code:

runBlocking {
            val client = HttpClient()

            val message = <http://client.post|client.post><Person> { //(path = "/path") {
                url("<http://localhost:8080/path>")
                contentType(ContentType.Application.Json)
                body = Person("James", "Smith")
            }
        }

...

Person

is

@Serializable

, should I not be setting it to the body of the post request like this? I assumed that, being

Any

,

JsonFeature

would know how to handle this? Can't find an example or details in ktor documentation.

Kind new here too... but how did you install the JsonFeature? Did you try

val client = HttpClient() {
   install(JsonFeature)
}

Though there isn't a specific example for iOS, there is an example of setting a request body on a post request here: https://ktor.io/clients/http-client/call/requests.html Also, the code you shared seems to indicate you are expected a person as the response given by the server, so ktor would be trying to convert the response of the server to a Person. If the response of the server isn't a person, then that could cause a problem.
