I'm new to Ktor and having a problem with receiving a post - I'm sending a really simple bit of JSON {"title":"AA","slug":"BB"} and I've got an equally simple Serialiable data class TestForm(val title: String, val slug: String). Posting the JSON from my web page gets a 415 Unsupported Media Type error. What am I likely to have got wrong in setting up ContentNegotiation?

Never mind... I hadn't set the Content-Type in the Javascript fetch() call. No frameworks being used here...
