openclaw - 💡(How to fix) Fix memory-core / active-memory: Bundled plugin dirName crash on Slack thread session keys containing colons

Summary

memory-core (and/or active-memory) crashes with Error: Bundled plugin dirName must be a single directory when processing Slack thread session keys that contain colons (:) in the directory name component.

Reproduction

1. Enable memory-core and active-memory plugins
2. Receive a message in a Slack thread
3. Session key is generated as e.g. agent:main:slack:channel:c0ahbfy1kam:thread:1778994536.784089
4. The plugin attempts to use part of this key as a directory name
5. Crash: Error: Bundled plugin dirName must be a single directory: c0ahbfy1kam:thread:1778994536.784089

Logs

lane task error: lane=main durationMs=233 error="Error: Bundled plugin dirName must be a single directory: c0ahbfy1kam:thread:1778994536.784089"
lane task error: lane=session:agent:main:slack:channel:c0ahbfy1kam:thread:1778994536.784089:active-memory:acfa4d4d0a2f durationMs=235 error="Error: Bundled plugin dirName must be a single directory: c0ahbfy1kam:thread:1778994536.784089"

Impact

• The agent receives the Slack message and bootstraps a session, but the lane crashes after ~230ms
• The agent cannot reply to any Slack thread — only top-level channel messages work
• Gateway restart clears stale sessions but the bug recurs on the next threaded message

Environment

• OpenClaw 2026.5.2
• Plugins: memory-core (enabled), active-memory (enabled), openclaw-oap (enabled)
• Channel: Slack (socket mode)
• macOS arm64, Node v22.22.2

Expected Behavior

Session keys containing colons should be sanitized (e.g. replacing : with _ or -) before being used as directory names in plugin internals.
