I uploaded a google docs folder from rclone 1.63.1 from documentserver 8.2.1.1, Linux Mint Cinnamon 21.1
Just about all docx documents that were from 1989 to 2010 uploaded and converted fine. All pdfs uploaded fine. Those docs from 2017 to 2024 failed with ‘You cannot upload a folder or empty file’.
If I upload individually the files that failed, they upload fine, even when showing a size of zero.
Being able to upload a google docs folder makes migrating to onlyoffice almost trivial, at least when it works. Since the uploads work fine when done individually, it seems an issue specifically with the folder upload compared to the individual upload.
Let me know if you need more information.
