Error Message

  1. Plugin/Core Version Guard: Prevent loading a plugin that requires a newer Core API. Show a clear startup error if plugin.apiVersion > core.apiVersion.
  2. Config Validation: Reject or warn on invalid visibleReplies values at config load time, not silently fall through to default behavior at runtime.

Root Cause

Root Cause (Verified)

API version mismatch: Discord Plugin 2026.5.4 calls formatChannelProgressDraftLineForEntry(), which does not exist in OpenClaw Core 2026.5.3-1. This causes a SyntaxError on every Discord message run during the delivery phase.

Fix Action

Solution

Option A: Downgrade Discord Plugin to match Core

openclaw plugins install [email protected]
openclaw config patch --raw '{"messages":{"groupChat":{"visibleReplies":"automatic"}}}'
openclaw gateway restart

Option B: Upgrade Core to match Plugin

openclaw update
# Then restart gateway

Code Example

openclaw plugins install discord@2026.5.3
openclaw config patch --raw '{"messages":{"groupChat":{"visibleReplies":"automatic"}}}'
openclaw gateway restart

openclaw update

Bug Report: Discord GroupChat replies invisible — Plugin/Core version mismatch (2026.5.3/2026.5.4)

Environment

  • OpenClaw Core Version: 2026.5.3-1 (2eae30e)
  • Discord Plugin Version: 2026.5.4 (locally installed, ahead of Core)
  • OS: macOS (Darwin 25.3.0 arm64)

Problem Description

After updating the Discord Plugin to 2026.5.4 while Core remained on 2026.5.3-1, assistant replies in Discord guild/group channels disappeared. The bot shows the typing indicator, generates a response (confirmed in session logs), but crashes during delivery with a SyntaxError — the message never appears in the channel.

Root Cause (Verified)

API version mismatch: Discord Plugin 2026.5.4 calls formatChannelProgressDraftLineForEntry(), which does not exist in OpenClaw Core 2026.5.3-1. This causes a SyntaxError on every Discord message run during the delivery phase.

Secondary issue: Config had visibleReplies: "all", which is not a valid value (accepted: "automatic", "message_tool", true, false).

Steps to Reproduce

  1. Install or update Discord Plugin to 2026.5.4
  2. Keep OpenClaw Core on 2026.5.3-1
  3. Send a message in any Discord guild channel where agent is bound
  4. Observe: Bot starts typing (indicator visible)
  5. Observe: Typing stops, but no message appears
  6. Check session logs: Response generated, but delivery crashed

Affected Channels

  • All Discord guild channels with agent bindings

Not Affected

  • Discord DMs (different code path)
  • Telegram, iMessage (unaffected channels)

Solution

Option A: Downgrade Discord Plugin to match Core

openclaw plugins install [email protected]
openclaw config patch --raw '{"messages":{"groupChat":{"visibleReplies":"automatic"}}}'
openclaw gateway restart

Option B: Upgrade Core to match Plugin

openclaw update
# Then restart gateway

Suggested Fixes

  1. Plugin/Core Version Guard: Prevent loading a plugin that requires a newer Core API. Show a clear startup error if plugin.apiVersion > core.apiVersion.

  2. Graceful Degradation: If formatChannelProgressDraftLineForEntry is missing, fall back to the older progress display method instead of crashing the entire delivery.

  3. Config Validation: Reject or warn on invalid visibleReplies values at config load time, not silently fall through to default behavior at runtime.

  4. Release Notes: Highlight plugin API changes prominently so users know to upgrade Core and Plugin together.

Verification

After applying Option A (plugin downgrade + config fix + restart):

  • Send message in Discord guild channel
  • Assistant reply appears automatically ✅

extent analysis

TL;DR

Downgrade the Discord Plugin to match the OpenClaw Core version or upgrade the Core to match the Plugin version to resolve the API mismatch issue.

Guidance

  • Verify the OpenClaw Core and Discord Plugin versions are compatible to prevent API mismatches.
  • Check the visibleReplies config value to ensure it is set to a valid option ("automatic", "message_tool", true, or false).
  • Consider implementing a version guard to prevent loading plugins with incompatible API versions.
  • Test the fix by sending a message in a Discord guild channel and verifying the assistant reply appears.

Example

To downgrade the Discord Plugin, run the following command:

openclaw plugins install [email protected]

Then, update the visibleReplies config value:

openclaw config patch --raw '{"messages":{"groupChat":{"visibleReplies":"automatic"}}}'

Finally, restart the gateway:

openclaw gateway restart

Notes

The provided solution assumes that downgrading the Discord Plugin or upgrading the OpenClaw Core will resolve the issue. However, this may not be the case if there are other underlying compatibility issues.

Recommendation

Apply workaround by downgrading the Discord Plugin to match the OpenClaw Core version, as this is a more straightforward and immediate solution.
