The new catch path logs/captures the raw axios error object, which can include request headers and leak the Slack bot token into logs/Sentry.

Pull request overview
This PR improves observability of Slack alert delivery failures in the backend helper slackPostMessage, so operational alerts don’t fail silently when Slack rejects a message or the HTTP request errors.
Changes:
- Adds detection/logging for Slack API “ok: false” responses (HTTP 200 but rejected by Slack).
- Adds error logging and Sentry reporting around Slack post failures.
- Introduces a Sentry dependency in the Slack helper to report alerting-channel failures without using the Winston logger (to avoid circular imports).

Axios 1.16.1 AxiosError toJSON config util.inspect console.error authorization header serialization Sentry @sentry/minimal 6.19.7 captureException AxiosError config
💡 Result:
In Axios 1.16.1, AxiosError.toJSON() is the standard way to serialize error details for logging or debugging [1][2]. Because AxiosError objects contain the request config—which includes sensitive headers like Authorization—logging the error object directly (e.g., via console.error or Sentry) can leak credentials [3][4]. To prevent this, use the redact configuration option in your request. When provided, Axios will mask specified headers (case-insensitively) at any depth when toJSON() is called [1][5]: axios.get('/user', { headers: { Authorization: 'Bearer token' }, redact: ['authorization'] }).catch(error => { // error.toJSON.config.headers.Authorization will be [REDACTED ] console.error(error.toJSON); }); Key technical details: - Serialization Safety: AxiosError.toJSON() produces a bounded snapshot of the error [6][7]. Recent updates ensure that complex objects like HTTP agents are replaced with '[Agent]' and streamed response bodies are marked as '[Readable]' to prevent CPU spikes or Out-of-Memory (OOM) errors during serialization [6][8]. - Sensitive Data: Relying solely on util.inspect or console.error on the raw AxiosError object remains risky because they may traverse the full object structure, including sensitive headers, bypassing the toJSON() redaction logic [3][4]. Always invoke error.toJSON() or specifically sanitize the object before logging [1][2]. - Sentry Integration: When using @sentry/minimal 6.19.7, passing an AxiosError directly to captureException may attach the full, unredacted error context [9][10][11]. To safely capture context, use the beforeSend hook in your Sentry initialization to sanitize the error or extract only the necessary response data [12]: Sentry.init({ beforeSend(event, hint) { if (hint?.originalException?.isAxiosError) { // Manually extract and attach only what you need event.extra = {...event.extra, status: hint.originalException.response?.status }; } return event; } }); Note: @sentry/minimal was deprecated in Sentry v7; its functionality was moved to @sentry/hub [13]. If possible, upgrade to a newer Sentry SDK version for improved error handling and type support [13].

Sensitive Data Exposure (CWE-532): Insertion of Sensitive Information into Log File
Reachability: External · Exploitability: Difficult
Do not log or capture the raw Axios error.
Axios retains the request config on rejected requests, including the Slack bearer token. Sanitize the error before passing it to console.error or Sentry.captureException, while preserving the non-throwing behavior.
