Unable to pass rootURI to palantir groovy language server

[sanketbajoria]

Sorry, for asking this naive question.
I am trying to integrate monacco-languageclient with groovy language server. I am getting below exception.
Either rootUri or rootPath must be set

I have tried setting up the rootUri to a dummy folder path
MonacoServices.install(editor, {rootUri: "file:///D:/git/monaco-languageclient/example/var"});

But still i am getting same error.

Please help me with this
