I'm trying to fill a form with Puppeteer on a webpage, the input has an id and I'm using it as a selector.

The ID is :

#loginPage:SiteTemplate:formulaire:login-field

When I get the selector from chrome it gives me that :

#loginPage3a SiteTemplate3a formulaire3a login-field

And wether I put the first or the second option in Puppeteer it spits me out this error :

Error: Evaluation failed: DOMException: Failed to execute 'querySelector' on 'Document': '#loginPage:SiteTemplate:formulaire:login-field' is not a valid selector.

Here is the code if needed :

(async () => 
 const browser = await puppeteer.launch(headless: false);
 const page = await browser.newPage();
 await page.goto('XXX');
 await page.click(GOTO_LOGIN_BUTTON_SELECTOR)
 await page.waitForNavigation(waitUntil: 'load');
 await page.waitFor(EMAIL_SELECTOR); // here
 await page.focus(EMAIL_SELECTOR);
 await page.keyboard.type(CREDS.email);
 await page.focus(PASSWORD_SELECTOR);
 await page.keyboard.type(CREDS.password);

 await browser.close();
)();

One option, for an ID like that, is to do as follows:

const EMAIL_SELECTOR = '[id="loginPage:SiteTemplate:formulaire:login-field"]';

Or, if that doesn't work, split it up as follows to work around the use of the ::

const EMAIL_SELECTOR = '[id*="loginPage"][id*="SiteTemplate"][id*="formulaire"][id*="login-field"]';

Hopefully one (or both) of those will help!

I'm not sure but I would drop the line await page.waitForNavigation(waitUntil: 'load');

And replace await page.waitFor(EMAIL_SELECTOR); // here

with await page.waitForSelector(EMAIL_SELECTOR);

And test to see if just using #login-field or other #loginPage > SiteTemplate > formulaire > login-field

I could be wrong as I'm still working this out too.
