This script uses the jsxapi library to send a command to a Cisco collaboration device.

1. const xapi = require('jsxapi'); imports the necessary library.
2. xapi.command(...) is the correct method in the jsxapi library to execute a command, such as an HttpClient Get.
3. The .command method returns a JavaScript Promise. The .catch() function is the standard way to handle errors or rejections in a Promise chain.
4. Finally, printHttp(...) is the function call that executes the defined script logic.

Cisco DevNet & jsxapi GitHub Repository (Official Vendor Documentation): The official jsxapi documentation demonstrates the standard usage pattern.

Connecting: The README.md shows the proper way to import and initialize the library is const xapi = require('jsxapi');. (URL: https://github.com/cisco-js/jsxapi, Section: "Usage")

Executing Commands: The documentation explicitly states that to send a command, you use the xapi.command(path, params) method, which returns a promise. (URL: https://github.com/cisco-js/jsxapi, Section: "API > xapi.command(path, params)")

Promise Handling: The examples show the use of .then() for success and .catch() for handling errors, which is the standard for JavaScript Promises. (URL: https://github.com/cisco-js/jsxapi, Section: "API > xapi.command(path, params)")
