Describe the bug
When I try to debug a Hack script in Visual Studio Code using vscode-hack extension, visual code debugger adapter launches and immediately dies. My visual code global settings.json configuration is as below:

"configurations": [
{
"name": "HHVM: Run Script",
"type": "hhvm",
"request": "launch",
"script": "${file}",
"hhvmPath": "/usr/local/bin/hhvm",
"hhvmArgs": ["--mode", "vsdebug", "--vsDebugPort", 8999],
"cwd":"${workspaceFolder}"
}
]

Closing, as this appears to be a configuration question about a third-party project: slackhq/vscode-hack#125
