openclaw - 💡(How to fix) Fix [Bug]: Discord DM fails with "Unknown Channel" in 2026.4.21 (regression from 2026.4.14) [1 comments, 2 participants]

In OpenClaw 2026.4.21, sending a DM (direct message) to a Discord user fails with the error "Unknown Channel".

TL;DR

The issue can likely be worked around by having the recipient send a message to the bot first, creating the DM channel.

Guidance

• Verify the regression by testing the same functionality in version 2026.4.14 to confirm it worked as expected.
• Attempt to send a DM after the recipient has initiated a conversation with the bot to see if the issue is resolved.
• Investigate changes in Discord channel/DM initialization or gateway sidecar handling in the 2026.4.21 update to identify the root cause.
• Consider reaching out to the OpenClaw development team to report the regression and seek a permanent fix.

Example

No code snippet is provided as the issue does not specify any code-related details.

Notes

The provided workaround may not be suitable for all use cases, especially if the bot needs to initiate conversations with users who have not previously interacted with it.

Recommendation

Apply workaround: Have the recipient send a message to the bot first, as this is the only known way to create the DM channel and allow the bot to send messages normally, until a permanent fix is available.
