what is the bug

All my STLs can't be found by VSCode. I checked and it's using package:// so it shouldn't be related to: #623.

The image below should show you my current setup:

1. My file structure with STLs & DAEs.

2. The way my URDF is loading, it is using package://, so should be working.

3. The previewed robot, only primitives are visible (not meshes).
   

4. The developer tools shows it fails to load the mesh file because of error 401 "unauthorized".
   

Repro steps

1. cd to my workspace
2. code
3. Select my URDF
4. F1 > ROS: Preview URDF

The thing is, in the vscode terminal, my workspace packages feel like it isn't loaded? When I type roslaunch go1_ then press tab, none appears. But I'm kinda sure they're loaded just fine, because if I open the URDF file while having the wrong working directory, it'd complaint that go1_description were not found:

So I'm confused about what did I miss.

expected behavior

All the meshes are loaded and visible
