requestHeartbeatNow with sessionKey silently skips for channel sessions (agent:main:slack:channel:*)
증상
api.runtime.system.requestHeartbeatNow({ sessionKey, reason, coalesceMs: 0 }) silently skips when targeting channel sessions (agent:main:slack:channel:*). No heartbeat turn runs, no error is logged, the system event sits in the queue indefinitely.
원인
OpenClaw gateway, skill, or agent configuration issue — root cause confirmed in the openclaw/openclaw issue tracker.
해결법
Reverted to POST /tools/invoke → sessions_send (with gateway.tools.allow: ["sessions_send"] + tools.sessions.visibility: "all" config). Dead code for requestHeartbeatNow preserved in plugin for fast migration.
