Failure rate increase on shop-checkout
Agent's plan
The shop-checkout service is experiencing a significant increase in failure rate, jumping from 0.1% to 18.4%, primarily due to a TypeError related to an undefined 'currency' property during checkout processing.
Customers attempting to complete purchases on the e-commerce platform are currently unable to do so, as the shop-checkout service is failing.
Recent deployment introduced a bug in checkout processing
90%A deployment of 'shop-checkout' from v4.1.9 to v4.2.0 occurred just one minute before the problem started (finding 3). The service's failure rate jumped significantly (finding 1). The specific error 'TypeError: Cannot read properties of undefined (reading 'currency') at calculateTotals' (finding 2) strongly suggests a code-level regression introduced by the new deployment.
rollback · Rollback shop-checkout service to previous stable version v4.1.9
This action directly addresses the leading hypothesis that the recent deployment (v4.2.0) introduced the bug. Rolling back to the previous version (v4.1.9) is the quickest way to revert the problematic code change and restore service functionality.
