I am trying to log all network requests in a page. My goal is to later filter for particular requests and check their initiator. The code below runs fine if I comment line 12 const request_initiator = interceptedRequest.initiator();. But the initiator is something really need. According to puppeteer's docs I am calling it correctly.

Here is my code:

const puppeteer = require('puppeteer');

(async() => {
    const results = [];
    const browser = await puppeteer.launch();
    const page = await browser.newPage();
    await page.setRequestInterception(true);
    page.on('request', interceptedRequest => {
        const request_url = interceptedRequest.url();
        const request_method = interceptedRequest.method();
        const request_payload = interceptedRequest.postData();
        const request_initiator = interceptedRequest.initiator();
        results.push({
            request_url,
            request_method,
            request_payload,
            request_initiator
        })
        interceptedRequest.continue();
    });
    await page.goto('https://testurl.com');
    await browser.close();
    return results
})().then(function(result) {
    console.log(result)
});

Here is the error I am getting:
