Sometimes BOT can’t find the HTML element due to which some activities(click & type into) does not work well and BOT stops. and when I check the HTML I see an extra argument added to the tag “uipath_custom_id”.
The UiPath’ s custom id appears when the selectors for the element aren’t very reliable. In this case you should try adding more elements to your selector while defining the activities such that the id tag is removed.
After you select an element to click, go to edit selector, use Ui Explorer to define the element with more/varied selectors.
If you are using latest studio versions then you have the option of Fuzzy Selectors. That should not let id appear and make the element easily recognizable.
