MoveTargetOutOfBoundsException problem with chromedriver version >74

Question

I don\'t know why ActionChains move_to_element() is not working with chromedriver >74.

(But it works on chromedriver 74 and geckodriver.)

Answer 1

move_to_element uses internally move_to

def move_to_element(self, to_element):
    if self._driver.w3c: # default in chromedriver 79
        self.w3c_actions.pointer_action.move_to(to_element)

def move_to(self, element, x=None, y=None):
    #...
    el_rect = element.rect
    left_offset = el_rect['width'] / 2
    top_offset = el_rect['height'] / 2
    left = -left_offset + (x or 0)
    top = -top_offset + (y or 0)

    self.source.create_pointer_move(origin=element, x=int(left), y=int(top))

The mouse pointer is moved by offset based on the element position. You are locating the element and then scroll it into view using JavaScript, so the offset is calculated by the wrong coordinates.

Removing the JavaScript scroll should solve the problem.
