What am I doing wrong? PHP extension works fine except for my MongoDB classes in the PHP Composer vendor hierarchy. vendor directory is in the root of the workspace. VSCode and extensions up to date. I've played with some extension settings (pathing to composer.phar etc.) but no luck.
jwoehr Thank you for reporting the issue.
It may be a bug. Please try running VSCode command (from menu -> view -> command palette):
Clear /vendor/ cache ...
If anything goes wrong, there will be a warning in the Output window, under the PHP Language Server tab.
