Summary

Cron jobs with delivery.mode: announce fail to deliver results via Discord DM when both Telegram and Discord channels are enabled.

Environment

• OpenClaw version: 2026.3.28 (f9b1079)
• macOS, launchd gateway
• Channels: Discord + Telegram both enabled

Reproduction

1. Have both channels.discord and channels.telegram enabled in config
2. Create a cron job with announce delivery:

   openclaw cron edit <id> --announce --channel discord --to "user:339338572354158602"
   

3. Run the job: openclaw cron run <id>
4. Job completes but delivery fails

Observed Behavior

Error alternates between two messages depending on config:

1. With --channel discord or --channel discord:default:

   Error: Unknown Channel
   

2. With --channel last:

   Channel is required when multiple channels are configured: telegram, discord
   Set delivery.channel explicitly or use a main session with a previous channel.
   

Expected Behavior

--channel discord --to "user:<id>" should resolve correctly and deliver to the Discord DM.

Workaround

Using --no-deliver (silent mode) works. The job runs fine, just no delivery.

Notes

• Delivery worked in earlier versions (pre-2026.3.28)
• The isolated cron session appears unable to resolve the channel reference even with explicit config
• Single-account mode (no accounts: block in discord config)
