flow-for-vscode breaks on WSL

[vedantroy]

I am trying to use WSL with the flow-for-vscode extension. However, I am getting the following error:

[babel\.flowconfig] Failed to start flow Error: (Failure "not localhost - file://wsl$/Ubuntu/home/vedantroy/babel")

Is this an error on my end or flow's end? For context, I am trying to work on the https://github.com/babel/babel repository, and I see that I can run the flow server with node_modules/.bin/flow.
