How can I send files with Ktor client and FormData in KotlinJS? I receive files as FileList (which contains the actual Files) from React Input of type file . But I haven't found a way to append them to FormData. I tried using the org.w3c.xhr.FormData but I get the error

IllegalStateException: Fail to serialize body. Content has type: class null, but OutgoingContent expected.

But when I try to use the Ktors io.ktor.client.request.forms FormData, there is no override for append that accepts File type
