Evidence: line 48 in `billing.ts` attempts to access `invoice.customerId`, indicating that the `customerId` property is being dereferenced, but the error message suggests it does not exist. Specifically, the error log line \"TypeError: Cannot read properties of undefined (reading \\\"customerId\\\")\" at `settleInvoice (billing.ts:48)` implies that the `customerId` is not present in the `invoice` object, likely due to an incomplete or missing customer association when the invoice was created.\n\nRanked alternative hypotheses:\n1. **Data corruption**: It is possible that the data in the invoice or customer database is corrupted, leading to missing or null `customerId` values.\n2. **API integration issue**: The error might be caused by an issue with the API that provides customer information, resulting in incomplete or missing customer data being passed to the billing service.\n3. **Deployment-related configuration issue**: The recent deployment of `billing-svc 1f4a` might have introduced a configuration issue that affects how customer data is handled or retrieved.\n\nNext debug steps:\n1. **Inspect the invoice data**: Run a query to retrieve the invoice data for the specific invoice that triggered the error (e.g., `SELECT * FROM invoices WHERE id = 8f2a`) to verify if the `customerId` is indeed null or missing.\n2. **Check customer association**: Investigate the customer association logic to ensure that invoices are being created with valid customer associations (e.g., `SELECT * FROM customers WHERE id IN (SELECT customer_id FROM invoices)`).\n3. **Review deployment changes**: Compare the changes introduced in the `billing-svc 1f4a` deployment with the previous version to identify any potential issues related to customer data handling or API integrations (e.g., `git diff .. billing.ts`)."},"createdAt":"2026-06-28 11:47:36.552169+00"}]}
