While checking website today which is developed using asp.net webform(.net 4.0) around 2014 showed design breaks after checking I noticed that there are some error in the console.
Not sure why this error suddenly started to show today, could it be due to bad ajax file or some sort of corruption as I'm getting similar error for other .net webform based website.

Use of getPreventDefault() is deprecated. Use defaultPrevented instead.
For even single .net based website I'm getting below error
WebResource.axd?d=pynGkmcFUV13He1Qd6_TZG4nAkbmoskOtxxp5ySS-SKn9PX36JMmpseXOU7BCTEiPJsUpsbpzfd66G07Bi3ozQ2&t=6362842281600
Worth mentioning that this error only happens on production server not the local server since this morning.
