Hi, at my ktor client I want to transform the server response to a custom one. I am intercepting HttpResponsePipeline.Transform for that. I want to know if we can parse error response from server as well at this point? Any help would be great! Code in thread.

client.responsePipeline.intercept(HttpResponsePipeline.Transform) { (info, body) ->
    val response = if (context.response.status == HttpStatusCode.OK) {
            //transform to success response
            SuccessResponse(body)
        } else {
           //read error response body?    
        }
    proceedWith(HttpResponseContainer(info, response))
}

val response: MyCustomResponse = client.get("some url")

I can have a success response as:

{
  "name": "NAME",
  "message": "MESSAGE"
}

and error response as:

{
  "error": "ERROR",
  "message": "MESSAGE"
}

You can do it if you disable default response validation by adding expectSuccess = false to the client's configuration. Also, SuccessResponse and ErrorResponse should implement the same interface MyCustomResponse .
