Extra details: the issue ONLY happens if the target object where the json is deserialized has a field of array type and the json contains that field with a non-array type.
If it's the other way around and the target object contains a non-array type field and that field in the json has a different type (numeric, array, etc) it will not crash and will be silently ignored.
