Description

Telescope's ClientRequestWatcher calls $response->body() on every HTTP response, which fully consumes non-seekable SSE stream bodies before Prism can read them.

This breaks the stream capability.

My current workaround to overcome this, add this before you instantiate the Agent:

if (class_exists(Telescope::class)) {
    Telescope::stopRecording();
}

Note: of course this will disable all telescope logging and monitoring for the agent requests.

Contributor guide

Research direction
Inspect ClientRequestWatcher to avoid calling body() on streamed responses, check if response body is a stream before consuming.
