Hello - my agent had some issues accessing Widgets & Blueprints when I tried using it:
Unreal error (-32000): widget_path is required

Seems like the TypeScript server is using short parameter names (widget, blueprint) in its Zod schemas, but the C++ UE5 plugin expects widget_path and blueprint_path.

Thanks for the report — you were right about the parameter-name mismatch between the server schemas and the plugin. v1.0.2 is now up with this fixed (widget_path / blueprint_path and the rest are aligned).

After downloading, re-run:

```

cd server

npm install

npm run build

```

Sorry for the trouble, and thanks for the clear repro.
