Hi @sentry[bot]! 👀

Thanks for flagging this Express.js "Cannot write headers after they are sent to the client" error from our desktop prod environment 🙌. This typically happens when an endpoint tries to send a response (res.send/res.json/res.status) after headers were already sent—often due to double-response in async middleware, error handlers firing after success paths, or unawaited promises.

Could you share:

• The full Sentry event with stack trace? (https://refly-ai.sentry.io/issues/7433191098/)
• Affected endpoint/route?
• Recent changes around line 19136 in index-qwPU6JX0.js (main process)

We'll triage promptly (24h SLA). Questions? Reply here!
