[error] AttributeError ( 'NoneType' object has no attribute 'getX' )
...
54: logger ( passed ) region = (last_match.getX(), last_match.getY(), last_match.getW(),

Apparently last_match is undefined or empty in that moment. Where was this meant to be set?

Eventually you should use getLastMatch().getX() etc.

It runs fine till this point- Self.log.passed, and passes the validation but stops with an error.

                     type("n", KeyModifier.ALT)
                    wait(3)
                    type("m")
                    wait(7)
                    if exists("packagertab.png"):
                            click("packagertab.png")
                            self.log.passed("New media packager tab - passed")
                    else:
                            self.log.failed("New media packager tab - failed")
                            wait(2)

this from my logger.py,

def passed(self, msg, *args, **kwargs):
  self.info('PASS: ' + msg, *args, **kwargs)

  #if self.isEnabledFor(logging.DEBUG) and len(getLastFoundImages()) != 0:
  if len(getLastFoundImages()) != 0:
    #source image
    #self.html_img("Source Image", common.cfgImageLibrary + '/' + getLastFoundImage())
    #matched image
    last_match = SCREEN.getLastMatch()
    region = (last_match.getX(), last_match.getY(), last_match.getW(), last_match.getH())
    self.screenshot(msg="Best Matches", folder='results', region=region)
    #score of match
    #self.info("Matched with score: %s" % last_match.getScore())

What is getLastFoundImages() ?

I suggest that you add a few debug statements, e.g. to check what SCREEN.getLastMatch() is at the moment when you try using it.

Why are you adding SCREEN at that moment? I do not see any need, if you did not use SCREEN in any other related part of the scripts.
