It's 2:47 AM when the alert fires. An RPA bot that processes thousands of invoices daily has crashed—again. The cause? Someone in IT renamed a database column from "vendor_name" to "supplier_name" during a routine schema update. The bot, built on rigid rules that expected exact field names, doesn't know how to adapt. It throws an exception and stops cold. By morning, a backlog of 3,000 invoices sits unprocessed, and three engineers are scrambling to patch the script before the finance team notices.
