Blank UI when launching device-farm plugin via launchctl (missing storage directory)

[RoyAlfiVerisoft]

I’m trying to run the Appium Device Farm plugin as a launchctl service on macOS, but although the plugin appears to load correctly, the UI never renders (just a blank screen). The logs show that it’s failing to read its storage directory:

Error: [node-persist][readDirectory] /Users/<my-user>/.cache/appium-device-farm/storage does not exist!
    at …/node-persist/src/local-storage.js:296:13
    …
[device-farm-main] Promise { <rejected> Error: [node-persist][readDirectory] /Users/<my-user>/.cache/appium-device-farm/storage does not exist! … }

Steps to Reproduce

1. Install appium-device-farm plugin under $HOME/.appium
2. Create a Launch Agent plist that runs appium --use-plugins=devices-farm at login
3. Start the service with launchctl load ~/Library/LaunchAgents/io.appium.device-farm.plist
4. Open http://localhost:4723/device-farm in browser → blank page

any help???
