adb.adb_protocol.InvalidResponseError: Incorrect remote id, expected 52728 got 52729

my use pull script

adb.Pull("/sdcard/screen.png", "screen.png")

Weird i look the self.adb is not implemented method

i try to look for print(dir(self.adb))

the return

['__class__', '__delattr__', '__doc__', '__format__', '__getattribute__', '__hash__', '__init__', '__new__', '__reduce__', '__reduce_ex__', '__repr__', '__setattr__', '__sizeof__', '__str__', '__subclasshook__']

thank for looking
