Hello! could you please give a simple example how do i set up the schema? Ultimately, I need it to generate AsyncApi.

typed web sockets is not suitable for me as it closes the connection on request decoding errors

What you’ll need to do in this case is use the `.requestSchema` / `.responseSchema` methods on the web socket output. The schema can be derived, though you’ll need to transform it so that it’s a schema for `WebSocketFrame`: this disables run-time validations, but the documentations should be ok. For example:

```plaintext
  case class MyFrame(data: String)
  val myWsOutput = webSocketBodyRaw(AkkaStreams)
    .requestsSchema(Schema.derived[MyFrame].as[WebSocketFrame])
  endpoint.out(myWsOutput)

```
