Debugging

This is a sample launch.json file you should have if you are using Visual Studio Code

{
    "version": "0.2.0",
    "configurations": [
        {
            "type": "node",
            "request": "launch",
            "name": "Debug API Gateway",
            "program": "${workspaceFolder}/node_modules/serverless/bin/serverless",
            "args": [
                "offline",
                "start"
            ]
