How can I prevent this ktor-client exception when the response type is nullable and the body is empty? ```ReceivePipelineException: Fail to run receive pipeline: NoTransformationFoundException: No transformation found: class JsHttpResponse -&gt; class ExerciseProgressDTO```

Hi, <@UGR59ATSS> . What version of ktor do you use?

```
implementation "io.ktor:ktor-client-js:1.1.3" implementation "io.ktor:ktor-client-json-js:1.1.3"
```

Though, maybe it will be solved if my body contains an empty json object instead? I'll give that a try too.

Nevermind, that gives me a MissingFieldException.

You can configure Jackson not to fail on empty beans `(disableFeature(DeserializationFeature.FAIL_ON_EMPTY_BEANS)`

My problem is on the frontend though, I want ktor to return null when my body is empty and my response type is nullable.

Ktor (as far as I can tell) only supports passing `KClass&lt;T&gt;`, which would mean that this is not possible. It would need some kind of Type Token to support this.
