Hi Josef,

Thanks for answering.
We are able to reproduce this issue at our end, and the missing information you are talking about are only dates (document created and modified dates).
Hence, we have logged this issues in our internal issue tracking system. As we get any update from the concerned team, we will update you accordingly.

Hi Josef,

The issue you reported will be fixed in any of our future releases. Until this issue is resolved, we would suggest you to use any other Java serialization/deserialization libraries that can convert Java Objects into JSON and back. You can use Gson and you may find this link helpful.

Serialization can be performed this way:
String data = gson.toJson(fileData);
try (FileWriter file = new FileWriter("D:/file.txt")) {
Please find the attached JSON output file and JSON view (screenshot) as well.

Have a nice weekend ahead.
Best Wishes
