Bug

The msteams plugin (v2026.3.22) crashes immediately on startup with:

[default] channel exited: Missing parameter name at index 5: /api*; visit https://git.new/pathToRegexpError for info

The plugin enters a crash-restart loop (auto-restart 1-10/10) and never becomes functional.

Environment

• OpenClaw: 2026.3.24 (cff6dc9)
• Node.js: v25.8.2 (upgraded from v25.7.0)
• OS: macOS (Darwin 25.3.0 arm64)
• Plugin: msteams 2026.3.22 (bundled + ClawHub version)
• Install method: Both openclaw plugins install @openclaw/msteams and direct load from dist/extensions/msteams

Steps to Reproduce

1. Install OpenClaw 2026.3.24 with Node.js 25.8.2
2. Configure msteams channel with valid credentials
3. Start gateway
4. Plugin crashes immediately with the path-to-regexp error

Analysis

The error Missing parameter name at index 5: /api* indicates that the Bot Framework SDK (or Express route setup) uses a wildcard pattern /api* that is incompatible with newer versions of path-to-regexp shipped with Node.js 25.8.x or the updated Express dependency.

The breaking change in path-to-regexp v8+ removed support for unnamed wildcard parameters (see https://git.new/pathToRegexpError).

Impact

• msteams channel is completely non-functional
• Does not affect other channels (Discord, etc.)
• All other Teams setup (Azure Bot, manifest, Funnel) works correctly

Expected Behavior

msteams plugin should start and listen on the configured webhook port.
