Bug Description

The Matrix plugin fails to load in v2026.3.2 because extensions/matrix/src/matrix/send-queue.ts imports KeyedAsyncQueue from the subpath openclaw/plugin-sdk/keyed-async-queue, but the corresponding JS file is missing from the build output. Only a .d.ts file exists at dist/plugin-sdk/plugin-sdk/keyed-async-queue.d.ts.

This is a build/packaging regression introduced in v2026.3.2 — the Matrix plugin loaded successfully in v2026.3.1.

Error

[plugins] matrix failed to load from .../extensions/matrix/index.ts:
Error: Cannot find module '.../dist/plugin-sdk/index.js/keyed-async-queue'
Require stack:
- .../extensions/matrix/src/matrix/send-queue.ts

Root Cause

1. package.json exports map declares ./plugin-sdk/keyed-async-queue → ./dist/plugin-sdk/keyed-async-queue.js
2. The .js file was not generated during the v2026.3.2 build (only .d.ts exists)
3. The tsx/ts-node loader used for extensions resolves the import incorrectly: instead of using the exports map, it resolves openclaw/plugin-sdk to dist/plugin-sdk/index.js and then appends /keyed-async-queue, resulting in dist/plugin-sdk/index.js/keyed-async-queue (treating index.js as a directory)

Note: KeyedAsyncQueue IS exported from the main plugin-sdk/index.js (as Ut in the rolldown bundle), so the class itself is available — just not at the subpath the extension expects.

Workaround

Patch the import in send-queue.ts to use the main module:

sed -i 's|from "openclaw/plugin-sdk/keyed-async-queue"|from "openclaw/plugin-sdk"|' \
  extensions/matrix/src/matrix/send-queue.ts

This works because KeyedAsyncQueue is re-exported from the main plugin-sdk/index.js.
