appium IOSDriver getSettings() throw NPE on appium server 15.

appium IOSDriver getSettings() throw NPE on appium server 15.

1. start appium, IOSDriver iosDriver = new IOSDriver(xx,xxx);
2. iosDriver.setSetting(Setting.IMAGE_MATCH_THRESHOLD, 0.8);
3. iosDriver.getSettings();
   then it throws NPE

Environment

Appium java client: io.appium:io.appium:7.1.0 / io.appium:io.appium:7.2.0
Appium version: 1.15.0
Node.js version: v11.2.0
Npm version: 6.4.1
Mobile platform/version under test: ios13.1
Real device or emulator/simulator: real device

Details

it's because that the setting "reduceMotion" is null in new appium server(1.15.0).
and then
ImmutableMap.builder().putAll((Map)Map.class.cast(response.getValue())) will throw NPE

This has been fixed in master, but not published

Thanks.
isn't it a server bug? I am wondering why the appium server responses with reduceMotion=false when I setSetting() but responses with reduceMotion=null when I getSettings();

[mykola-mokhnach]

As far as I can remember this has been done deliberately to show that this setting has its default value and has not been changed explicitly yet

@imurchie Could probably confirm

Hello, @imurchie any clarification? @mykola-mokhnach when do these changes be merged and published in maven https://mvnrepository.com/repos/central. thanks!
