Well, that was interesting. An unclear timeout (after 10 seconds) on requests that streamed the response (with `respondBytesWriter` ) using the Netty Engine. Initial tests using `curl` did not trigger the failure.

Turns out it was caused by the Compression plugin, combined with a Netty `responseWriteTimeoutSeconds`  that defaults to 10 seconds.

So the fix was to either increase that timeout in the Netty configuration,
```embeddedServer(Netty, env) {
    responseWriteTimeoutSeconds = 60
}```
or to disable compression for the requests that use `WriteChannelContent`

```install(Compression) {
  condition {
    it !is OutgoingContent.WriteChannelContent
  }
} ```

Postman gave a `socket hang up` error, browser gave an `ERR_EMPTY_RESPONSE`, and nothing was visible in the ktor logging
