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%, immediately following a recent deployment of version v4.2.0. The failures are characterized by a TypeError related to reading 'currency' in the checkout totals calculation.
The 'shop-checkout' service is directly affected, preventing users from completing purchases and potentially impacting revenue. The problem appears contained to this service.
Recent deployment introduced a critical bug
90%A new version (v4.2.0) of 'shop-checkout' was deployed just one minute before the problem started (Finding 3). The failure rate spiked dramatically after this deployment (Finding 1). The specific error message 'TypeError: Cannot read properties of undefined (reading 'currency')' (Finding 2) strongly suggests a code change in the new version is mishandling data, leading to the observed failures.
rollback · Rollback 'shop-checkout' service to previous stable version v4.1.9
Given that the failure rate increase and specific error message correlate directly with the deployment of v4.2.0, rolling back to the previously stable version v4.1.9 is the most direct and effective way to mitigate the issue and restore service functionality.
