Using androidx.navigation:navigation-safe-args-gradle-plugin:2.3.2

when if compile my projet with a boolean array argument and set its default value to @null

<argument
    android:name="multiChoiceCheckedItems"
    android:defaultValue="@null"
    app:argType="boolean[]"
    app:nullable="true" />

I get an error:

androidx.navigation.safeargs plugin failed
Execution failed for task ':app:generateSafeArgsDebug'.
> androidx.navigation.safeargs plugin failed.
   Following errors found: 
  W:\Projects\HelloBirdieAndroid\app\src\main\res\navigation\navigation_main.xml:136:9 (navigation_main.xml:136): 
  error: 'boolean[]' is a simple type and cannot be nullable. Remove app:nullable="true" from the argument.

Although documentation do not mention any problem with boolean array and explicitly mention that any array argument can have only one default value "@null". https://developer.android.com/guide/navigation/navigation-pass-data#supported_argument_types
