It might be just me - but I'm having mixed results using CSS selectors to correctly identify the area to be captured.

For example, using div#PDP_productPrice on https://www.boots.com/no7-men-anti-ageing-bundle, throws the error

2020-11-08T18:05:46.717Z ERROR The function passed to Apify.main() threw an exception:
2020-11-08T18:05:46.719Z   Error: Cannot get screenshot (screenshot selector is probably wrong)
2020-11-08T18:05:46.721Z       at /home/myuser/main.js:64:15
2020-11-08T18:05:46.722Z       at processTicksAndRejections (internal/process/task_queues.js:97:5)

which in my mind is not expected behaviour. Am I right?

Also, improve the error message with a link to the snapshot

Current version allows only one url, adding the option to check multiple urls at same time will be useful.

Hi, I tried your content checker and it didn't work in the basic "try it" version. I am new to apify, so I understand there maybe a problem with the way the Docker is started, but I couldn't figure out how to fix it on my own. I have added the failed run url along with the log: https://my.apify.com/view/runs/pcRvjQdbiwYJrse1S

I am getting a timeout in most of the runs

Page is reachable and loads fast in a regular browser :S

Hi there,

I've been able to use this promising actor on Apify, but checking another URL throws me this error:

2021-05-17T05:04:37.952Z INFO  Saving screenshot...
2021-05-17T05:04:37.956Z ERROR The function passed to Apify.main() threw an exception:

What works:

(taken from the documentation)

    {
      "url": "https://www.apify.com/change-log",
      "contentSelector": "[class^=change-log__MonthBox-]",
      "sendNotificationTo": "[email protected]",
      "proxy": {
        "useApifyProxy": false
      },
      "navigationTimeout": 30000
    }

Not working

     {
        "url": "https://www.leboncoin.fr/recherche?text=Neuf",
        "contentSelector": "[class^=styles_Listing_]",
        "sendNotificationTo": "[email protected]",
        "proxy": {
          "useApifyProxy": false
        },
        "navigationTimeout": 30000
      }

I've double-checked and the selector exists on the page, at least when I visit the website with my own browser.
The website Leboncoin ships some Bot blockers from Datadome, maybe is the scraping bot from Apify blocked?

Note that also tried with "useApifyProxy": true - the same error occurs..

Any hint?

Allows you to do some calculations between data in a function that returns a boolean (takes previous and latest state), and use the current behavior if not provided

Hi - as an addition to the web front end's inputs, please could you add a toggle which allows the actor to send an alert if the content hasn't changed since last time. The opposite of what's there right now might be useful for other folks too. Thanks -A.

Hello,

Congratulations on the work, I really liked the project.

I did some tests and the printscreen seems to be partial, is there any way to increase it?

Using lodash get, use CheerioCrawler instead of Puppeteer to load a JSON endpoint and access a path either using a dot notation path like data.edges.0.price or an array of strings. If it's a 'fork' material, let's close the issue

• include blocked message/screenshot to emails

Hi there,

Content Checker works great, thanks!

but I receive many false positives because of the timestamp being updated, triggering a notification.
To be clear, I get emails because the post date changed from "Posted 1 hour ago" to "Posted 2 hours ago"

Is there a way to ignore such modifications?
