const select = require('puppeteer-select');
const FORM = {
USERNAME_SELECTOR: '#username',
PASSWORD_SELECTOR: '#password',
BUTTON_SELECTOR: '.btn__primary--large.from__button--floating'
};
const CREDENTIALS = {
USERNAME: 'Username',
PASSWORD: 'password'
};

SEARCH_SELECTOR: '#global-nav-search',
KEYWORD: '',
CONNECT: '#ember52'
};
const escapeXpathString = str => {
const splitedQuotes = str.replace(/'/g, `', "'", '`);
return `concat('${splitedQuotes}', '')`;
};
const clickByText = async (page, text) => {
const escapedText = escapeXpathString(text);
const linkHandlers = await page.$x(`//a[contains(text(), ${escapedText})]`);
if (linkHandlers.length > 0) {
await linkHandlers[0].click();
} else {
throw new Error(`Link not found: ${text}`);
}
};
(async () => {
const browser = await puppeteer.launch();
const page = await browser.newPage();
await page.goto('https://www.linkedin.com/login?trk=guest_homepage-basic_nav-header-signin', {waitUntil: 'networkidle0'});
await page.click(FORM.USERNAME_SELECTOR);
await page.keyboard.type(CREDENTIALS.USERNAME);
await page.click(FORM.PASSWORD_SELECTOR);
await page.keyboard.type(CREDENTIALS.PASSWORD);
await page.click(FORM.BUTTON_SELECTOR);
await page.waitForNavigation();
await page.click(SEARCH.SEARCH_SELECTOR);
await page.focus(SEARCH.SEARCH_SELECTOR);
await page.keyboard.type(SEARCH.KEYWORD);
await page.keyboard.press('Enter');
await page.waitForNavigation();
clickByText(page,`people`);
await page.waitForNavigation();
await page.screenshot({path: 'verify16.png', fullPage: true});
console.log("Current page:", page.url());
//from here
const invitation = await select(page).getSend('span:contains(Send)');
await invitation.click();
//getting error
await browser.close();
})();```
I cannot click on connect button -> I have also to add notes and do for all other connections.
