Error when used with vscode remote extensions

[aufflick]

When you are using the VSCode remote extension (https://code.visualstudio.com/docs/remote/remote-overview) you get the "Running ... failed" popup. The remote extension host log shows this error, I guess because path isn't a simple string when running remotely?

[2019-10-23 16:55:52.129] [exthost] [error] TypeError [ERR_INVALID_ARG_TYPE]: The "path" argument must be of type string. Received type undefined
