Microsoft.SharePoint.Client.ServerException when a list item have a 2G attachment

Question

In SharePoint online, the size limit of an attachment is 2G. However, when we tried to get FieldValuesAsText property with that list item, we got this exception:

Unhandled Exception: Microsoft.SharePoint.Client.ServerException: Value was either too large or too small for an Int32.

 at Microsoft.SharePoint.Client.ClientRequest.ProcessResponseStream(Stream res
ponseStream)
   at Microsoft.SharePoint.Client.ClientRequest.ProcessResponse()
   at Microsoft.SharePoint.Client.ClientRequest.ExecuteQueryToServer(ChunkString
Builder sb)
   at Microsoft.SharePoint.Client.ClientRequest.ExecuteQuery()
   at Microsoft.SharePoint.Client.ClientRuntimeContext.ExecuteQuery()
   at Microsoft.SharePoint.Client.ClientContext.ExecuteQuery()

I wrote a test program to reproduce this error, it is below. As the error is at the SharePoint Online server side, how do I debug this? I guess on the server side it use Int32 to convert the file size(2G), which leads to this error. Is there's a way to fix this?

Also this problem can be reproduced in this way: create a sub folder in the one drive, put files with total size>2G. As the 'Folder" is actually an item, that exception also occurs.

            ListItemCollection items = docList.GetItems(query);

            // Retrieve all items in the ListItemCollection from List.GetItems(Query).

            foreach (ListItem listItem in items)

                ctx.Load(listItem, li => li.DisplayName, li => li.Id);
                ctx.ExecuteQuery();
                Console.WriteLine(listItem.DisplayName + listItem.Id);

                //ServerException when file size is 2G
                FieldStringValues fieldStringValuesText = listItem.FieldValuesAsText;
                FieldStringValues fieldStringValuesHtml = listItem.FieldValuesAsHtml;
