Cannot run uiautomator dump command after updating to appium 1.9.1

[dtsvirkun]

Some windows are not accessible via esspresso driver ( eg. Selecting picture fromgallery), so we use uiatomator from devices to get window dump and then click by coordinates:

Map<String, Object> args = new HashMap<>();
 args.put("command", "uiautomator");
 args.put("args", Lists.newArrayList("dump"));
String output = driver.executeScript("mobile: shell", args);

For some reason it stopped working after updating to new appium 1.9.1, herelog out put:

In addition I can run this command manually and it works, but when test is in progress (appium is run for app), manual command execution also does not work.
