Remove `/analytics` from the internal URL** Your backend connects directly to Superset (container-to-container), bypassing Traefik. The `SUPERSET_APP_ROOT="/analytics"` config makes Superset's `AppRootMiddleware` expect `/analytics` in the path and strip it before routing. However, internally at port 8088, Superset routes still work at the root. The TLS error suggests something is going wrong with the connection — but more importantly, the URL should not include the subpath for internal calls since you're not going through Traefik: ``` # ❌ Current SUPERSET_URL=http://superset:8088/analytics # ✅ Correct for internal container-to-container SUPERSET_URL=http://superset:8088 ``` Wait — actually, since you set `SUPERSET_APP_ROOT="/analytics"`, Superset's `AppRootMiddleware` **does** expect the `/analytics` prefix on all incoming requests even on port 8088. So `http://superset:8088/analytics` is technically correct for internal calls. **2. The real problem: the TLS error** The error says "Client network socket disconnected before secure TLS connection was established" — this means Node.js is trying to establish a **TLS (HTTPS) connection** to `superset:8088`, even though your URL starts with `http://`. This typically happens when: - Your Node.js app has a **global HTTPS agent** or proxy configured that forces TLS on all connections - There's an **environment variable like `HTTPS_PROXY` or `NODE_TLS_REJECT_UNAUTHORIZED`** affecting fetch behavior - Your NestJS app or its HTTP client library is configured to upgrade connections to HTTPS **Check these:** 1. Do you have any `HTTPS_PROXY` or `HTTP_PROXY` environment variables set on your backend container? 2. Is there any global `fetch` or HTTP agent configuration in your NestJS app that forces HTTPS? 3. Try adding this to your backend service to verify: ```typescript console.log('Connecting to:', `${this.supersetUrl}/api/v1/security/login`); console.log('HTTPS_PROXY:', process.env.HTTPS_PROXY); console.log('HTTP_PROXY:', process.env.HTTP_PROXY); ``` 4. As a quick test, try a simple `fetch` from inside the backend container to confirm connectivity: ```bash docker exec <your-backend-container> node -e "fetch('http://superset:8088/analytics/health').then(r => r.text()).then(console.log).catch(console.error)" ``` **3. Minor issue: empty username** Your guest token request has empty `username`, `first_name`, and `last_name`. Superset 5.0+ requires a **non-empty `username`** for guest tokens to work properly, especially with RLS: ```typescript user: { username: "guest_user", // Must be non-empty first_name: "Guest", last_name: "User" } ``` The core problem is that Node.js is attempting a TLS handshake on what should be a plain HTTP connection. Check your proxy/agent configuration. <!-- Dosu Comment Footer --> *To reply, just mention [@dosu](https://go.dosu.dev/dosubot?utm_source=github&utm_medium=bot-comment&utm_campaign=github-comment-footer-20260415&utm_content=reply-with-mention&utm_term=apache%2Fsuperset).* --- Docs are dead.
