Please help

Hi Mohana,

This error normally pops up if the robot is unable to locate the selector which was initially selected while developing the bot. Please do the following:

  1. Check if the selector is dynamic if yes make use of ? or * whichever suits your requirement.
  2. Make use of attach browser

If possible could you please share the xaml file for further debugging.

Thanks Illango, Not sure how to make the selection as dynamic. Please help


post your selector here… ppl can take a look and help


Eg. Please find below two selectors. Both selectors are looking similar except aaname part.
<html title='ACME System 1 - Dashboard' />
<webctrl aaname='Accounts' parentid='dashmenu' tag='BUTTON' />

We will use Wild cards (* and ?) or will pass variable names into selectors to make dynamic selectors.

<html title='ACME System 1 - Dashboard' />
<webctrl aaname='Work Items' parentid='dashmenu' tag='BUTTON' />

To make it to dynamic selector in below way.

<html title='ACME System 1 - Dashboard' />
<webctrl aaname='*' parentid='dashmenu' tag='BUTTON' />

Thanks , I did the same but still getting the error.


At the time BOT running, Is the web page opened or not ?

Go to Target section and try to validate that selector and then highlight it and see.

Thanks for your reply. this is my first code in uipath :), Yes at the time of running I m seeing the webpage is opened . The error is after that only.


Click on Attach to Live Element and indicate it again.


Is it possible to access that site from my side?

Fantastic, It works. The CSV has been generated successfully. But not any rows has been captured :frowning:

unfortunately its the intranet site where you cant access …


Have you scrapped data properly from web page ?

yes, I used get full text to get the 3 detaills(Name, designation, PAname) from my intranet site.


If it is structured data (Like Table format) , Then use data Scraping. It will be easy way to get all data.

Thanks , lakshman. As I mentioned earlier this is my first hands-on at Uipath. I have mentioned my sequence of activities on my original post. Not sure where to change to data scraping. If you can guide me that will be great. Please help. thanks


Regarding Point No. 5,6
Please take screenshot of the data and show me once. Then I will check whether it is structured data or not.

please see the screenshot to use data scraping for structure data (table data)

@lakshman : Its sensitive cant share.
Just simple page it has left side picture of the person : name PA NAme: rosy
Designation: director Designation: Pa to

picture : person : name picture: Pa name : christy
Designation : assistant director Designation:Pa to assitant director

something like this
