The \"path\" argument must be of type string. Received type undefined

[bstaletic]

• I have searched through existing issues
• I have read through docs
• I have read FAQ

Info

• Platform: Arch Linux for me, but a user of my client reported the issue on macOS
• Vetur version: Commit hash: f2c73f7, but our user reported the problem after running npm install --production with this package.json
• VS Code version: None, using YouCompleteMe in vim

Problem

As soon as I start the server, I get, similarly to #1402, The \"path\" argument must be of type string. Received type undefined

Reproducible Case

Currently not using any configuration of the server, but the same happened when I tried to use the default configuration from here.

The json exchange from my client's side looks like this:

2019-08-26 23:37:34,879 - DEBUG - TX: Sending message: b'Content-Length: 431\r\n\r\n{"id": "1", "jsonrpc": "2.0", "method": "initialize", "params": {"capabilities": {"textDocument": {"completion": {"completionItemKind": {"valueSet": [1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25]}}}}, "initializationOptions": {}, "processId": 23433, "rootPath": "/Users/nbossard/OtherProjects/mahali/front/webapp", "rootUri": "file:///Users/nbossard/OtherProjects/mahali/front/webapp"}}'

Thanks for your detailed report. This should be fixed in latest release of VLS.
