Description

When cron jobs execute and try to deliver messages via the announce system, delivery fails with error:

Steps to Reproduce

1. Create a cron job with (no delivery field)
2. Wait for cron to execute
3. Message delivery fails

Expected Behavior

The cron job should deliver messages to the configured target (e.g., Telegram).

Actual Behavior

Error: "Action send requires a target."

Environment

• OpenClaw version: 2026.2.25
• Gateway: running on loopback (127.0.0.1:18789)
• Telegram channel configured and working for normal messages

Workaround

Sending messages directly via the agent (non-cron) works fine. Only the automatic delivery from cron jobs fails.

Logs

This appears to be a regression - the delivery system is not passing the target parameter when attempting to send messages from cron jobs.
