Same issue (or related?) after update to 1.3.7.

@mofizul21 those laravel global namespaced facades like DB don't have a concrete definition in the workspace and cannot be indexed. To get around this you can use https://github.com/barryvdh/laravel-ide-helper or if you prefer set intelephense.diagnostics.undefinedTypes to false in settings.
@mstroink that's a strange one. It looks like it has found the definition to provide the hover. Can you share some code that reproduces the issue?
Closing as original issue has a solution. @mstroink if you are still experiencing this please open a new ticket with a code example.
Try use Illuminate\Support\Facades\DB; instead of use DB;
