Usages of Buffer fail with "Error:"Buffer is not defined"" - Known Error

Usages of Buffer fail with "Error:"Buffer is not defined"" Description Usages of Node.js built-in, Buffer, fail in Yokohama and later releases. The error, "Error: "Buffer" is not defined." is thrown.

Steps to Reproduce

Call the following module code from a BG script:

import { gs } from "@servicenow/glide"

const text = "Hello, World!"; const byteLength = Buffer.byteLength(text, 'utf8');

gs.info(`Text: "${text}"`); gs.info(`Byte length: ${byteLength}`);

export { byteLength };

Workaround The workaround is to add a polyfill for Buffer to the Fluent project. Please note, there is a defect in the ServiceNow SDK that would prevent this workaround. That defect will be resolved starting in SDK version 4.1.1

Install the 'buffer' polyfill package, "npm install buffer" Require the polyfilled implemenation at the top of your module that depends on that functionality, e.g. "const { Buffer } = require('buffer');" Related Problem: PRB1964445
