Hello, I am writing a Plugin in Ktor, the idea of this Plugin is to first check if Internet is available, if not cancel request and throw error, and when we receive response we check if the status is 401 in that case retry the call after making a new token.

scope.requestPipeline.intercept(HttpRequestPipeline.State) {
    println("MyNewPlugin : works the scope ${context.method}")
    context.header(HttpHeaders.UserAgent, feature.agent)
}
scope.responsePipeline.intercept(HttpRequestPipeline.State) {
    println("MyNewPlugin : works the scope ${context.response.status}")
}

I wrote this in the install function to test the Plugin for request and response pipeline but it crashes with this error

Caused by: io.ktor.util.pipeline.InvalidPhaseException: Phase Phase('State') was not registered for this pipeline

The second interceptor should be on the phase HttpResponsePipeline.State instead of HttpRequestPipeline.State because the response pipeline is intercepted.
