Hello! I am using sttp-client v3.8.11 with http4s v0.23.17.  
I have a configured route

```auto
HttpRoutes
  .of[F] {
    case GET -> Root / "users" / userId => ???
}

```

And I am getting the following error while sending a GET request to the `http://0.0.0.0:80/users/user_1234`:

```auto
sttp.client3.DeserializationException: No usable value for id

```

What could be the root cause?

It would be useful to see the code that you use to perform the request. It seems you are trying to deserialise the response body as a JSON, and the response doesn’t contain an `id` field as the deserialisers expect. But I’m only guessing, it might be something different as well
