Greptile Summary

This PR fixes a critical, 100% reproducible bug where createFeishuWSClient() passed no wsConfig to Lark.WSClient, causing the Lark SDK to throw "Cannot read properties of undefined (reading 'PingInterval')" and making WebSocket mode entirely non-functional for all enterprise users.

The fix is minimal and correct — adding wsConfig: { PingInterval: 30, PingTimeout: 5 } directly to the WSClient constructor call, matching the Lark SDK's expected configuration shape.

• The chosen values (30 s ping interval, 5 s timeout) are standard WebSocket keep-alive defaults and are consistent with Lark SDK documentation examples.
• The change is well-scoped: it touches only the one constructor call that was broken and does not affect the HTTP client, caching logic, or any other path.
• No issues found; the PR is safe to merge.

Confidence Score: 5/5

• This PR is safe to merge — it is a minimal, targeted fix for a well-understood crash with no risk of regression.
• The change is a single-constructor property addition that directly addresses the root cause (the Lark SDK unconditionally dereferencing wsConfig). The values are reasonable defaults (30 s interval, 5 s timeout). No existing behaviour is modified; the fix only adds what was previously missing.
• No files require special attention.

Review: ✅ LGTM

Clean XS fix. Adding WebSocket keep-alive config (30s ping interval, 5s timeout) prevents stale Feishu WS connections from silently dying. No breaking changes, no side effects. Ship it.

Thanks for the review! 🦞
