I am trying to use clipboard in order to copy 'longlat' to the clipboard by passing it through the function 'copyData()'. However, it keeps giving me errors.
This is the error (1. Clipboardy.writeSync not a function and 2.UnhandledPromiseRejectionWarning) :
(node:16596) UnhandledPromiseRejectionWarning: TypeError: clipboardy.writeSync is not a function

This is my code
const clipboardy = (...args) => import('clipboardy').then(({default: clipboardy}) => clipboardy(...args));
const puppeteer = require("puppeteer");
const url = "https://www.google.com/";
async function StartScraping() {
await puppeteer
.launch({
headless: false,
})
.then(async (browser) => {
const page = await browser.newPage();
await page.setViewport({
width: 2000,
height: 800,
});
page.on("response", async (response) => {
if (response.url().includes("General")) {
const location = await response.text()
let intlong = location.indexOf("Example:")
const longlat = location.substring(intlong, intlong + 46)
console.log(longlat);
copyData(longlat)
}
});
await page.goto(url, {
waitUntil: "load",
timeout: 0,
});
});
}
function copyData(data1) {
clipboardy.writeSync(data1)
}
StartScraping();
cy.window().its('navigator.clipboard')
.invoke('readText').then((data) => {
console.log(data);
})
Should do the trick. If you are using cypress on the browser

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:

currently I'm struggling with fingerprint in my previous project i solved this in this way:
const test = async (req, res, next) => {
// other code
const FingerprintJS = require('#fingerprintjs/fingerprintjs');
const store = require('store')
FingerprintJS.get({
preprocessor: function(key, value) {
return value
}
},function(components){
let values = components.map(function (component) { return component.value });
let device_id = FingerprintJS.x64hash128(values.join(''), 31);
store.set('print', { device: device_id })
});
await new Promise(resolve => setTimeout(resolve, 1000));
// other code
};
But now I cant set it up to work.. I'm getting error in console.log :
(node:4940) UnhandledPromiseRejectionWarning: TypeError: FingerprintJS.get is not a function

Your getFile function takes an argument. You are invoking it in getFileFromNet but not passing the argument in.
I set up a loop inside of an async function to iterate over a list of URLs. The data is coming from an .xls file converted to .json. My goal is to capture a screenshot of each URL in the array but I keep getting UnhandledPromiseRejectionWarning. Any ideas how how i might achieve this? Any help is appreciated!
The Code:
const puppeteer = require("puppeteer");
const excel = require("./excel");
const data = excel.data;
async function run(arr) {
for (let i = 0; i < data.length; i++) {
const url = data[i]["Seller"];
const sku = data[i]["Seller Name"];
const browser = await puppeteer.launch();
const page = await browser.newPage();
await page.setViewport({
width: 1000,
height: 840,
deviceScaleFactor: 1
});
await page.goto(url, { waitUntil: "load" });
await page.screenshot({ path: `screenshots/${sku}.jpg` });
await browser.close();
}
}
run(data)

Your code seems correct to me. Did you try looking at what is coming out in data Seller and SellerName? I am guessing that you have issues in data. As you are not asserting anything you need not close the browser each time. Checkout the following snippet.
const puppeteer = require('puppeteer');
(async () => {
const data = [{"sellerUrl" : "https://www.amazon.com/",
"sellerName" : "amazon"
},
{"sellerUrl" : "https://www.ebay.com/",
"sellerName" : "ebay"
},
];
const browser = await puppeteer.launch();
const page = await browser.newPage();
for(const x of data){
await page.goto(x.sellerUrl, { waitUntill: 'networkidle2'});
await page.screenshot({path: `${x.sellerName}.jpg`});
}
await browser.close();
})();
in my async function i use Promise.all but for some reason its not defined or something here is the function
async function check_available_money() {
global_browser = await puppeteer.launch({headless: false, args: ['--no-sandbox', '--disable-setuid-sandbox']});
const page = await global_browser.newPage();
await page.setViewport({width: 1000, height: 1100});
var setting = {'username': 'aa', 'password': 'bb'};
try {
await page.goto('https://example.com/login', {timeout: 90000})
.catch(function (error) {
throw new Error(' TIMEOUT 1 ');
}
);
await page.$eval('#username', (el, setting) => el.value = setting.username, setting);
await page.$eval('#password', (el, setting) => el.value = setting.password, setting);
console.log(tab_id + ' -> SUMITING LOGIN FORM ');
await Promise.all(
page.$eval('form', form => form.submit()),
page.waitForNavigation()
)
console.log(tab_id + ' -> SUMITING LOGIN FORM DONE ! ');
}
catch (e) {
await page.close();
console.log(e);
}
}
i get error from this part
await Promise.all(
page.$eval('form', form => form.submit()),
page.waitForNavigation()
)
if i remove await Promise.all and just type
await page.$eval('form', form => form.submit());
await page.waitForNavigation();
it works ok

Promise.all takes an iterable, not multiple arguments. It tried to iterate your first argument, but that didn't have a [Symbol.iterator] method - "undefined is not a function". Pass an array:
await Promise.all([
page.$eval('form', form => form.submit()),
page.waitForNavigation(),
])
