Hi, What is correct way of handling empty response? When executing

PUT

request, api returns an empty body response but all types of ktor requests have a return type. To satisfy it, have created an empty data class, however getting an error when executing such request:

io.ktor.client.call.NoTransformationFoundException: No transformation found: class <http://io.ktor.utils.io|io.ktor.utils.io>.ByteBufferChannel (Kotlin reflection is not available) -> class xx.yy.api.NoContent (Kotlin reflection is not available)

. I’d guess serialization process is confused when mapping an empty response to data class. Any ideas how to fix it?

you can use

client.put<Unit>(url)

Thanks @Rustam Siniukov. Seems it worked out.
