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.
