UI

What happened?

After deployment, homepage can render blank in browser. F12 console shows:

Uncaught (in promise) TypeError: Cannot read properties of undefined (reading 'status')

Root cause is in frontend global request interceptor (cmdb-ui/src/utils/request.js):

• code path uses error.response.status without guarding when error.response is undefined
• this happens on network failures / CORS / backend-not-ready cases, causing uncaught runtime exception and white page

Expected behavior:

• interceptor must safely handle missing error.response and error.config
• UI should show generic request error and continue rendering instead of crashing

Fix submitted:

• normalized response/config/status access with safe defaults
• replaced direct chained access to guarded variables
• adjusted route/path read to avoid undefined property access

Patch commit:

• 2dd019c47 (fix(ui): guard axios error object access to prevent blank-page crash)

PR containing fix:

• security: API hardening and dependency vulnerability reduction (rescan 2026-03-08) #769
