Hi, I got throw error "Microsoft.AspNetCore.NodeServices[0] EXCEPTION: Cannot read property 'querySelector' of undefined" and so on.

My project use Asp Net Core + Angular JS. this throw error on library D3 query selector. I had struggle to find out this and eventually I realize the web load on the first time throw this error.

Ex:

I create 'A' component chart base on NVD3.
then I load on 'A' component at home
run localhost:5000/home
I got this error.

I have try using lazy load, async component, dynamic component that always throw error. This is doesn't make sense because I have try on angular 2 with webpack-server-dev working component and also put component on different page and working as well.

I thought was d3 lib or types issue, but it wasn't. because it was working without asp.net core.

Please help or suggest.

Thanks.
