How to make the query-string package work in Jest

Since the query-string package only supports ESM (ECMAScript Modules), it may not work correctly with Jest. This can result in an error message like SyntaxError: Cannot use import statement outside a module when running tests.

Add the following code to the jest.config.js file to fix this issue.

 "transformIgnorePatterns": [
    "node_modules/(?!(decode-uri-component|filter-obj|split-on-first|query-string)/)"
  ],
