when set containerDefaultToNull to false. eg data
data will init as new ArrayList<>().
but when we set data as null in request

}public void setData(List<@Size(min = 1, max = 64)String> data) {
this.data = data;
}data was override to null.
epxected as empty array,should be follow example

if(data== null){
return;
}
this.data = data;
}
