Error: strict mode: unknown keyword: "afterRequest"

[Harsh062]

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;
        ^

    at Array.forEach (<anonymous>)

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

Seeing the same issue with Node v20.10.0. Only reference to afterRequest I can find is within the har-schema package.

@austineady @Harsh062 I believe you're getting this error because the version of the ajv you're using is 8 while version 6 is needed for httpsnippet. If you do downgrade to 6, the error should go away. Interestingly enough, ajv is not defined as dep for httpsnippet while it's been used. It's only defined as dependency within har-schema, and I' guessing ajv v8 has some breaking changes.
