[Platform][OpenRouter] Streaming doesn't work

[jenky]

It appears that the OpenRouter streaming returns the result as SSE. As a result, json_decode does not work with non-JSON payloads.

This is the code that I used

$response = new StreamedResponse();

// $agent platform is open router

$response->setChunks($agent->call($messages, ['stream' => true])->getContent());
$response->headers->set('Content-Type', 'text/event-stream');
$response->headers->set('Cache-Control', 'no-cache');
$response->headers->set('Connection', 'keep-alive');
$response->headers->set('X-Accel-Buffering', 'no');

Uncaught Symfony\Component\HttpClient\Exception\JsonException: Syntax error for "https://openrouter.ai/api/v1/chat/completions". in /app/vendor/symfony/http-client/Response/CommonResponseTrait.php:90

The response
