JavaScript not working in browser automation

Posted on by SeniorJoker

function ExecuteScript() {
var sources = Array.from(document.getElementsByClassName('gallery-favorite'), div => div.getAttribute('data-id'));
return sources;
}

It works in developer tools console in browser but not with Power Automate. How can I find what is wrong?

It just hangs on forever like it's actually working. Browser Edge.

Not sure why it "hangs on forever." But here is one thing to keep in mind...

The PAD Run JavaScript action documentation specifies that the return variable be a text value. Because the Array.from() method returns an array you would likely get a return value from the PAD Run JavaScript action of "[Object object]", if you do get it to run.

If you do get Array.from() to run you could try returning JSON.stringify(sources). This would get you a JSON string version of your variable sources that you could process further in PAD.

Not that was the problem. Nothing worked at all. Even alert('Text'). Browser internal vpn extension was guilty. When I took out VPN to system level problem gone. Extension somehow affected page. But thanks for trying to help anyway.

@SeniorJokerdid you submit a bug report to power automate?
I had a similar issue with VPN last week and disabling the VPN fixed the issue.

Because so many VPNs require MFA these days, I just started a thread requesting more options for configuring the browser instance for situations like this. I can link you to the thread if you would like.

JavaScript browser automation it's broken on all PAD after ver. 2.26 you will always get [object Object].
May be related to the new browser extension.
Use an older version of PAD ver. 2.25 or ver 2.26 and will work perfectly fine.
