If the attribute does not exist on the element, an empty string will be stored
Use blank text if element is missing
If selected, Browserflow will use an empty string as the attribute if the element does not exist
By default, Browserflow will wait for the element to appear and exit with an error if the element cannot be found
This is useful when an element appears inconsistently (e.g. when looping through a list of elements where some elements contain a particular piece of data but others don't)
