Exception Handling behaviour


I want to know the exact difference between ‘uipaht.core.Selector not found Exception’ and ‘uipath.core.Selector Operation Exception’ and uipath.activities.selectorexception.’
Can you any one help me out ASAP.
urgent …

uipaht.core.Selector not found Exception : This exception comes when you are trying to point an element but that element is not at all present on the screen. That means if i say in layman term You are following an incorrect address. You can follow this link : https://activities.uipath.com/docs/try-catch

Thanks Rashmi,

Do you have any idea about the remaining two exceptions?
