Description

The logo in the Gateway Dashboard header shows a broken image icon when accessing via the /webchat/ path.

Environment

• OpenClaw version: 2026.2.6-3
• OS: Windows 11 with WSL2 Ubuntu
• URL: http://localhost:18789/webchat/chat?session=agent%3Amain%3Amain

Expected behavior

The OpenClaw logo should display in the header.

Actual behavior

A broken image placeholder is shown. The logo path returns HTML (200 OK, Content-Type: text/html) instead of the actual SVG file.

Reproduction

1. Start the gateway
2. Navigate to http://localhost:18789/webchat/chat
3. Open DevTools → Network tab
4. Observe that favicon.svg requests return text/html instead of image/svg+xml

Investigation

bash

Root path works correctly:

curl -s -I 'http://localhost:18789/favicon.svg'

Content-Type: image/svg+xml ✓

Webchat path returns HTML instead:

curl -s -I 'http://localhost:18789/webchat/favicon.svg'

Content-Type: text/html; charset=utf-8 ✗

The webchat route handler catches all requests and returns the SPA HTML, preventing static files from being served correctly at that path.

Suggested Fix
Serve static assets before the webchat SPA catch-all route, or use an absolute root path for the logo.
