Workaround for Control UI assets error after OpenClaw 2026.3.22 upgrade
Error and solution for OpenClaw 2026.3.22 upgrade
A user on r/openclaw shared a workaround for the "Control UI assets not found" error that appears after upgrading to OpenClaw version 2026.3.22. The error message states: "Control UI assets not found. Build them with pnpm ui:build (auto-installs UI deps), or run pnpm ui:dev during development."
Steps to fix on macOS with Homebrew Node
The solution involves preserving the control-ui folder during the upgrade process:
- First, install the beta version:
npm install -g [email protected] - Copy the control-ui folder from:
/opt/homebrew/lib/node_modules/openclaw/dist/control-ui - Upgrade to the stable release:
npm install -g openclaw@latest - Paste the control-ui folder back into the new installation directory
The user notes that the same approach should work on other systems—the key is locating the control-ui folder in the OpenClaw installation directory after the beta install and restoring it after the stable upgrade.
