email delivery is not awaited on the navigation request: after path/flag updates
commit, enqueue notification work in a bounded background job, return control
immediately for getConnectedScenes, updateStateVariables, and the 403 response,
and handle sendEmail retries and timeouts within the background job.

- Around line 12-29: Update the email template definitions, especially
EmailTemplate.YOUR_TURN, to HTML-escape dynamic name and scenarioName values
before interpolating them into html; apply the same protection to other dynamic
values in these templates as needed. Keep the surrounding markup static and
perform encoding at the template/send boundary rather than relying on validation
during scenario or group creation.

🌐 Web query:
For resend-node version 6.18.1, what official API supports aborting or timing out an emails.send request?
💡 Result:
As of resend-node version 6.18.1, there is no official, type-supported API for aborting or timing out an emails.send request via the SDK's public contract [1]. While the underlying implementation uses the Fetch API—which supports the AbortSignal interface—the resend-node SDK does not currently expose a signal parameter in its TypeScript request options [1]. Consequently, attempting to pass a signal, such as AbortSignal.timeout(ms), will result in a TypeScript error, even though it may technically function at runtime by being passed through to the fetch call [1]. If you need to manage the lifecycle of an email send request: 1. Request Cancellation: Resend provides an official emails.cancel API [2]. This is used to cancel an email that has already been scheduled for a future delivery (e.g., using the scheduledAt parameter) [2]. It is not intended for aborting an active HTTP request during the initial send call [2]. 2. Network Timeout: Because the SDK does not officially support request cancellation, you must rely on external wrappers or the default behaviors of your Node.js environment to handle network timeouts. You should avoid wrapping the call in a way that attempts to cancel the request without proper support, as the SDK is not designed to handle abort signals in its current public API [1]. The Resend team is aware of requests to officially support AbortSignal in the SDK, but as of version 6.18.1, it remains an unofficial, non-type-safe passthrough [1].

🌐 Web query:
site:github.com/resend/resend-node 6.18.1 emails.send timeout AbortSignal Resend client fetch
💡 Result:
In the resend-node SDK, the emails.send() method internally performs a fetch request, and the SDK's architecture allows it to accept and propagate an AbortSignal for timeout or cancellation purposes, even if it is not explicitly exposed in the official TypeScript type definitions for CreateEmailRequestOptions [1]. To implement a timeout for resend.emails.send(), you can pass an AbortSignal via the options object. Although TypeScript may flag signal as an unknown property on the request options, it is passed through to the underlying fetch call at runtime [1]. Example usage: const controller = new AbortController; const timeoutId = setTimeout( => controller.abort, 15000); // 15 seconds timeout try { await resend.emails.send({ from: 'you@example.com', to: 'user@example.com', subject: 'Hello', html: '
World
', }, { signal: controller.signal } as any); // Cast as any to bypass TypeScript checks } finally { clearTimeout(timeoutId); } Alternatively, you can useAbortSignal.timeout(15000) if your environment (Node.js 18+) supports it [1]: await resend.emails.send({ from: 'you@example.com', to: 'user@example.com', subject: 'Hello', html: 'World
', }, { signal: AbortSignal.timeout(15000) } as any); Note that this is currently an unofficial passthrough [1]. You should check the official resend-node GitHub discussions or repository for updates regarding native, typed support forAbortSignal [1].
Citations:
🌐 Web query:
site:resend.com/docs resend-node timeout AbortSignal emails.send
💡 Result:
The current resend-node SDK (the official Node.js package) does not natively expose a dedicated AbortSignal parameter within the options object for the resend.emails.send method [1][2]. The SDK is designed to return a standardized object containing either { data } or { error }, rather than throwing errors for network-level failures or request cancellations directly in the typical way [1][2]. If you need to implement a timeout or cancellation mechanism, you should handle this at the network request level by wrapping your asynchronous call in a promise that includes a timeout or by using a custom HTTP client implementation if the SDK's abstraction is insufficient for your specific environment requirements [1][2]. However, according to official documentation, the primary method for error handling should involve checking the returned { error } object for API-level issues, and using standard JavaScript/Node.js mechanisms for managing raw network request lifecycles if external timeouts are necessary [1][2]. For standard use cases, the SDK handles API requests, and you should rely on its returned error responses for flow control [1][2]. If you encounter network-level timeouts, those would typically appear as exceptions outside of the standard { data, error } return structure [2].

Abort each active Resend request when its 10-second limit expires. Promise.race() only rejects the wrapper; it does not cancel sendEmail(), so stalled fetches remain active after notifyNextRole() returns. Pass a per-send AbortSignal through sendEmail() to the second emails.send() request-options argument. Do not place it in the email payload.

Forward asynchronous database errors.
When User.findOneAndUpdate rejects, this bare async handler does not call next. Express 4.21 does not forward returned promises, so the central errorHandler is not reached and the request may remain pending. Wrap the handler with handle or catch the error and call next(err).

Firebase authentication stores the verified token UID in req.body.uid, but the handler uses the caller-controlled req.params.uid to select the database record. An authenticated caller who knows another UID can therefore change that user’s notification preference. Use req.body.uid for the update filter.

Use an explicit patch result for failure handling.
usePatch returns response?.data on success and err.response?.data on failure. Therefore, res?.status checks the response body, not the HTTP status. If a failed body has no status field, the optimistic value remains and no error appears. Make usePatch expose success separately or throw on failure, then restore or refetch the saved value.
