VS Code openHAB Extension!

I’ve recently started using this, but I don’t have full syntax checking. Also clicking on preview gives Error command’openhab.basicUI’not found

I’m running an APT-GET installed Snapshot build 1216

My user settings are:

{"openhab.host": "xxx.xxx.xxx.xxx",
 "openhab.port": 8080,
 "openhab.useRestApi": true,
 "openhab.username": "",
 "openhab.password": ""
} 

xxx.xxx.xxx.xxx is the ipAddress of my OpenHAB machine

In Workspace settings is the folder path to my OpenHAB machine, and an empty field called “settings”
Folder Settings are empty.

To get it working I just added the server address and left the rest as defaults, only adding the extra when it didn’t work.

What am I missing?
