 This configuration contains the following attributes:
 
 * `type` - specifies the type of the configuration. Set to `node` for a Node.js configuration.
+* `protocol` - specifies the Node.js [debugger wire protocol](https://code.visualstudio.com/docs/nodejs/nodejs-debugging#_supported-nodelike-runtimes). Note that the inspector protocol is supported in Node.js v6.3 (or v6.9 for Windows) or later. For early versions, omit this property. In that case, a legacy debugger protocol will be used. Legacy protocol is well known for its issues with source map support, therefore newer versions of Node.js are recommended.
 * `request` - specifies the request type. Set to `launch` since this configuration launches a program.
 * `name` - specifies the name of the configuration.
 * `program` - path to a JS file that will be executed. In this case, it is the TestCafe module.
