We have a production incident. The /api/payments/process endpointis returning 500 errors for ~15% of requests. This started approximately30 minutes ago.Help me investigate:1. Check the git log for any recent deployments (last 24 hours)2. Look at the payment processing code in src/api/payments/3. Check if there were any dependency updates recently
Claude Code 會檢查程式碼和最近的變更。在它工作的同時,在手機瀏覽器中打開你的監控儀表板檢查:
錯誤率是穩定的、上升的還是下降的?
所有實例都受影響還是只有部分?
失敗的請求是否有規律?
Claude Code 可能發現的問題: 3 小時前的一個提交將 Stripe SDK 依賴從 v12.1.0 更新到了 v13.0.0,其中包含了破壞性的 API 變更。
Compare the Stripe SDK v12 and v13 changelog.Check our payment processing code for any API calls that changedbetween versions. Focus on the payment intent creation andconfirmation flow in src/api/payments/processor.ts.
Claude Code 會分析程式碼並識別具體的不相容問題。典型的發現:
Found the issue. In Stripe SDK v13, the `payment_intents.create()` methodchanged its error handling behavior:- v12: Returns { error: { type, message } } for card declines- v13: Throws StripeCardError exception for card declinesOur code in processor.ts:45-52 checks for `result.error` but doesn'tcatch the new exception type. When a card is declined, the uncaughtexception propagates as a 500 error.This explains the 15% error rate — approximately 15% of paymentattempts involve card declines (expired cards, insufficient funds, etc.)that now throw uncaught exceptions.
Revert the Stripe SDK update. Change package.json to pinstripe at v12.1.0. Create a commit with message:"hotfix: revert Stripe SDK to v12 (fixes payment 500 errors)"
核准步驟: Claude Code 會請求核准修改 package.json 和執行 npm install。在核准卡片中查看變更並核准。
Fix the payment processing code to handle both the legacy errorresponse format and the new exception-based error handling inStripe SDK v13.Specifically:1. Wrap the payment_intents.create() call in a try/catch2. Catch StripeCardError and convert it to our standard error format3. Keep the existing result.error check as a fallback4. Add a test case for the card decline scenarioCommit with: "hotfix: handle Stripe v13 exception-based card decline errors"
Check the deployment status. Then help me verify:1. Run a test request against the production payment endpoint2. Check if the error rate has started decreasing3. Look for any new error patterns in the last 5 minutes
