Error: strict mode: unknown keyword: "afterRequest"

I am getting the below error when executing the basic example provided in the docs in my NodeJs project:

/Users/harsh/Desktop/http-snippet-demo/node_modules/ajv/dist/compile/index.js:120
        throw e;
        ^

Example Code:

const express = require('express');
const { HTTPSnippet } = require('httpsnippet');

const app = express();

const snippet = new HTTPSnippet({
  method: 'GET',
  url: 'http://mockbin.com/request',
});

const options = { indent: '\t' };
const output = snippet.convert('shell', 'curl', options);
console.log(output);

const server = app.listen(8000, '0.0.0.0', () => {
  console.log('Example app listening at http://%s:%s', server.address().address, server.address().port);
});

httpsnippet version in package.json file: ^3.0.1
NodeJs version: 18.17

I am getting the same error via CLI as well when executing the below command:
httpsnippet example.json --target shell --client curl --output ./examples

使用 issue 中报告的版本，通过文档所述的基本示例和 httpsnippet example.json --target shell --client curl --output ./examples 命令复现该失败。检查 package.json 中的依赖配置和 CLI 入口点，然后跟踪堆栈跟踪中显示的验证路径。当文档所述的两条调用路径都不再因未知的 afterRequest 关键字而失败时，即视为完成。
