Hi Nitin,
I have followed steps which mentioned in document.
Sign up for a Dynamics 365 Business Central sandbox.
Download Visual Studio Code.
Download the AL Language extension.
Press Ctrl+Shift+P to open the User Settings window; here you can modify the telemetry settings.
Press Alt+A, and right after, Alt+L to trigger the AL Go! command, choose a path to a new empty folder and which version to run. Then choose Microsoft cloud sandbox as the server.
After running that HelloWorld.al programme , it's giving me error : Error: The package could not be created.
Below pasting whole error for u r reference :
