Hi. Do you have our Pro Advanced package which is required to use Treeview plugin? Which version of MDB5 do you use? Because there was a bug with Treeview which has been fixed in 3.8.1 release. See the changelog here https://mdbootstrap.com/docs/standard/getting-started/changelog/#v3-8-1. And it would be nice to have a snippet showing this bug https://mdbootstrap.com/snippets/ in order to help you. It is really hard without your code.

Could we have any update about this issue? I'm working in Visual Studio 2022 with .Net 6 and typescript and I got the same problem. I modified some of your files to be sure "document.body" is not null when getting jQuery but another issue appears after this and it's not possible to fix everything (because I have to write in minified files).

@neocheck How to recreate this problem? Could you prepare a snippet with it?

In my case, the problem was I needed to declare the scripts in the head. When I changed them from the head to the bottom of the body before "@RenderSection" the rest of the errors disappeared. By the moment. I didn't get this problem using .Net Core 3.1 with your previous version of MDB pro in others projects.
