Office AddIn Excel custom function not run correct

I am trying to implement Excel addin custom functions.
First, I refer this doc Tutorial: Create custom functions in Excel, after run this from VS Code, the custom function auto generated add did not show up when I type in Excel cell.
For the auto generated project, it contains command, taskpane and functions, and i found Configure your Office Add-in to use a shared JavaScript runtime, it seems I need to configure the shared runtime. After configuring the shared runtime by following this doc, I am able to see the add function in excel cell, but, it keeps #BYSY!, and return error below in webpack windows.

How can I run a custom functions in excel?
