Step 07 using external rest api

'ClassCastException {message_8yp7un$_0: "Illegal cast" ' at fetchVideo

val response = window
.fetch("https://my-json-server.typicode.com/kotlin-hands-on/kotlinconf-json/videos/$id")
.await()
.json()
.await()
return response as Video

This at least cleared the issue
return window
.fetch("https://my-json-server.typicode.com/kotlin-hands-on/kotlinconf-json/videos/$id")
.await()
.json()
.await().unsafeCast<Video>()

Thanks for pointing this out.
In the last iteration, we've moved from the unsafe cast to using kx.serialization as a serialization framework, which does away with this problem entirely. :)
