Inject Js Script 'IFRAME': TypeError: Cannot read properties of null (reading 'children')

[Bhavesh_Batra]

Javascript working Fine in Chrome Inspect, but showing error from Inject Js Activity

This is the Script :-
var button_div = document.getElementById(“main-content”)
button_div.children[button_div.childElementCount-1].click();

This is the Error :- Inject Js Script ‘IFRAME’: TypeError: Cannot read properties of null (reading ‘children’)

My guess is it’s not a zero-based index, so using the count - 1 is causing it to try to interact with an object that doesn’t exist.

[Bhavesh_Batra]

Please suggest the solution…

[postwick (Paul Ostwick)]

Try it without the -1

Or maybe button_div.children isn’t returning anything

[Bhavesh_Batra]

var button_div = document.getElementById(“main-content”) is returning empty

@Bhavesh_Batra

Is the id you are searching is correct?

cheers

[Bhavesh_Batra]

Yes sir, it is working fine in Chrome Inspect but not in UiPath

Inject JS to find Display or Visibility of element on webpage

the returned uielement (variable box in your case) wil be assigned to invoke js target property element (refering to screenshot: here it is similar uiElement) [grafik] I would suggest to implement the javascript method signature not with changed name and implementing it with Function(element, input){—} input configured as described above
