Module FAQs
Can we track if a WhatsApp message failed?↓
Yes, the system logs response payloads and delivery statuses (Sent, Delivered, Failed) in a diagnostic history log.
How does the QR watchdog timer prevent server memory leaks?↓
When a QR code request initiates, the gateway starts a 60-second watchdog timer. If Puppeteer remains unauthenticated after 60s, the connection is aborted, closing the browser context and purging memory buffers.
How does the system resolve Windows EBUSY directory file-lock crashes?↓
The cleanup utility wraps 'fs.rmSync' commands in a try-catch retry logic. If files are locked by active Puppeteer threads, the system logs a non-blocking warning and ignores the deletion failure.
Are the PDF sharing links sent via WhatsApp secure?↓
Yes. Invoices and purchase orders are stored in private cloud buckets. The gateway generates temporary presigned URLs matching a 15-minute expiration window to block unauthorized exposure.
How does the persistent tray categorize in-app notifications?↓
Each notification record maintains a 'type' field (mrr, leave, bid). The UI leverages state hook arrays to dynamically filter records at the query level.
Does the WhatsApp gateway support delivery and read receipts?↓
Yes. The gateway checks receipt events sent by the headless browser. If the recipient has read receipts enabled, the system updates the log status from 'Sent' to 'Read'.
