    Hey,

     

    I found out what is the error.

     

    First I was using a date time library function what returns the current time when the object is null. So the time I printed on the console actually was null.

    So I searched the community with this new insight and I found this post, which is exactly my problem:

    BoxItem.Info returns null for various properties

    So you can't get the created at from the item BoxFile.Info directly. Here is how it works:

    1. make a new BoxFile object using the ID of the BoxFile.Info
    2. from this new BoxFile object get again the BoxFile.Info
    3. on this BoxFile.Info object you can now get the created at time stamp

    So it is not a bug, it is rather on misleading design.

     

    Here is the changed code

    for (BoxItem.Info itemInfo : folder) {
        if (itemInfo instanceof BoxFile.Info) {
            BoxFile.Info fileInfo = (BoxFile.Info) itemInfo;
            System.out.println("  File: " + fileInfo.getName());
    
            // new part - first get the BoxFile and then again the BoxFile.Info of that
            BoxFile boxFile = new BoxFile(api, fileInfo.getID());
            BoxFile.Info newBoxFileInfo = boxFile.getInfo();
            DateTime curCreatedAt = new DateTime(newBoxFileInfo.getCreatedAt());
    
            DateTimeFormatter dateTimeFormat = DateTimeFormat.forPattern("yyyy-MM-dd HH:mm:ss");
            System.out.println("    created_at: " + dateTimeFormat.print(curCreatedAt));
        }
    }

    String[] childrenFields = {"name", "createdAt", "size"};

    Iterable<BoxItem.Info> infos = folder.getChildren(childrenFields);

     

    "size" gets populated but not "createdAt". Better to get a new BoxFile.Info object from the id

    to fetch the "createdAt"
