[Bug]: NEXT_PUBLIC_API_URL Configuration Breaks All API Calls

[kaiyu96]

Affected area

Settings

Summary

The environment variable NEXT_PUBLIC_API_URL in .env.example includes an incorrect /api prefix, causing all HTTP requests to the Knowhere API to fail with 404 Not Found.

Problems:

• API calls are routed to wrong URL path
• All Dashboard features that call the API fail silently
• Error messages don't clearly indicate the root cause

Current Configuration:

# .env.example
NEXT_PUBLIC_API_URL=http://localhost:5005/api

How It Breaks:

In server/external-api/request.ts:

const url = `${env.NEXT_PUBLIC_API_URL}${path}`;
// When path = "/v1/auth/list"
// Result: http://localhost:5005/api/v1/auth/list  ❌ (404)
// Expected: http://localhost:5005/v1/auth/list    ✓ (200)

Browser

Chrome

Reproduction steps

1. Deploy Dashboard with .env.local having NEXT_PUBLIC_API_URL=http://localhost:5005/api
2. Navigate to Dashboard (localhost:3000)
3. Open browser DevTools (F12) → Network tab
4. Try to list API keys or perform any API operation
5. Expected: 200 OK response
6. Actual: 404 Not Found with response body: {"detail":"Not Found"}
7. Check network tab: request URL shows http://localhost:5005/api/v1/auth/list
