Visual Studio Code show "the command line is too long"

Please include steps needed to reproduce the bug, along any relevant sections of the log file, located at `node_modules/.lsp/debug.log`

I open the code https://github.com/Wonder-Technology/Wonder.js/tree/dev, run ```npm install``` and ```npm run watch```, the compile is OK,.But the editor show the error on each file.The error is the command ling is too long.

[debug.log](https://github.com/jaredly/reason-language-server/files/5193170/debug.log)

Reproduce the problem in the Wonder.js dev tree with `npm install` followed by `npm run watch`, then inspect `node_modules/.lsp/debug.log` and the linked log for the command-length error. Done means the error no longer appears when opening files in Visual Studio Code.
