openclaw - 💡(How to fix) Fix Feishu plugin v2026.4.20 fails to start: bot ping API returns 404 or timeout [2 comments, 3 participants]

Problem

After upgrading to OpenClaw 4.24, the Feishu channel plugin (v2026.4.20) fails to initialize. The gateway starts but all Feishu accounts fail with:

AxiosError: timeout of 10000ms exceeded
  url: 'https://open.feishu.cn/open-apis/bot/v1/openclaw_bot/ping'

or

404 Not Found
  url: 'https://open.feishu.cn/open-apis/bot/v1/openclaw_bot/ping'

The gateway log shows:

[error]: [feishu[main]]: bot info probe timed out after 10000ms; aborting startup
[gateway] feishu: abort signal received during startup preflight; stopping startup

Environment

• OpenClaw: 4.24 (2026.4.24)
• Feishu plugin: 2026.4.20
• Host OS: macOS
• Node: 22.22.1

Root Cause

The feishu plugin v2026.4.20 introduced a new bot identity preflight check (fetchBotIdentityForMonitor) that calls POST /open-apis/bot/v1/openclaw_bot/ping. If this request fails (timeout or 404), the plugin aborts startup entirely.

In contrast, feishu plugin v2026.4.15-beta.1 handles probe failures more gracefully — it logs an error but continues startup:

bot info probe timed out after 10000ms; continuing startup

Workaround

Manually replacing the feishu plugin files in 4.24 with those from 4.15 (feishu plugin v2026.4.15-beta.1) allows the gateway to start successfully. The plugin compatibility field "minHostVersion": ">=2026.4.10" in v2026.4.15-beta.1 confirms it is compatible with 4.24 host.

Questions

1. Is the /open-apis/bot/v1/openclaw_bot/ping endpoint expected to exist on all Feishu bot configurations?
2. Should the ping failure be fatal (aborting startup) or non-fatal (continuing with a warning)?
3. Should this be filed as a bug in the feishu plugin (@m1heng) rather than the core?
