I'm implementing Testing Library with Puppeteer and I was trying to use an environment variable, DEBUG_PRINT_LIMIT, to limit the length of the HTML printed to console in case of failure.

But for some reasons, the variable environment is just ignored by the library...

My project:

package.json

I am trying to click on the settings button in Google but I am struggling with the page.click() method because I do not know what class or id to use to navigate to the tools button.

This is the code I have so far:

I have this code :

so launching a chrome instance using these flags ;

I'm trying to use Puppeteer to click on a button.

The webpage in my script has a grid which acts as a calendar and each date is a button. The issue is that every date button is of the same class type and I so I couldn't single out a specific date.

I tried to identify the buttons by the aria label it still wouldn't work.

I then tried to click the "Go Forward 5 Days" button using the aria label and that didn't work either.

I have read that it might be available by iterating through the parent element in the HTML tree and then just picking the one that I want (example: putting the calendar element into a variable and then choosing the child I want[7]), but this really isn't ideal and I'm hoping there is another way.

Puppeteer is very useful and I have been able to scrape many different parts of my site. I know its very easy easy to get by selection and xpath but how would I get by xpath or selection and print out "hey"

I am trying to print a header section to each page of a PDF that gets generated. I'm also using pdf-merger to merge together multiple PDFs. Right now when I execute this code the PDF generated contains multiple documents, as expected. However the Header section I'm adding only seems to show up in the 2nd and 5th of the documents that are part of the full PDF. I cannot tell from looking at my code why that is happening. I would assume the Header would be added to each of the documents.

First question: why am I noticing the behavior I am. Understand that would help me know what to adjust. Second question: How can I adjust this code so that the Header is added to each of the pages of the document?

Here is the section where I pass options to page.pdf():

I am trying to take screenshots of each section in a landing page which may container multiple sections. I was able to do that effectively in "Round1" which I commented out.

My goal is to learn how to write leaner/cleaner code so I made another attempt, "Round2".

In this section it does take a screenshot. But, it takes screenshot of section 3 with file name JSHandle@node.png. Definitely, I am doing this wrong.

I'm doing some Puppeteer web scraping and for some reason, when I put in a proxy flag generated by creation of an account on this site (https://proxy.webshare.io/proxy/list?), it causes the waitForSelector() to get a TimeoutError. Not sure what the issue is because if I don't use a proxy, no error is thrown.
