moveItemsToTrash Api error SyntaxError: "undefined" is not valid JSON

Doing some massive cleanup I try to move to trash all items from one folder.

Here is the log:

Source read complete Found items: 17466 Items to process: 17466 Moving 17466 items to trash Processing 500 items Processing 500 items Processing 500 items Processing 500 items Processing 500 items moveItemsToTrash Api error SyntaxError: "undefined" is not valid JSON SyntaxError: "undefined" is not valid JSON

Then I retry the same operation: Source read complete Found items: 15466 Items to process: 15466 Moving 15466 items to trash Processing 500 items Processing 500 items Processing 500 items Processing 500 items Processing 500 items moveItemsToTrash Api error SyntaxError: "undefined" is not valid JSON SyntaxError: "undefined" is not valid JSON

So it seems that retrying helps and hopefully I will be able to delete it all after several retries.
