Yet another Upload failed: undefined

I have been running cells version 3.0.6 for three months and it happens only two times, which I had to restart with “systemctl restart pydio” to fix this issue.

I have read old topic about this error and the current solution I have is to periodically restart pydio.service via systemd variables:

cat pydio.service

Restart=always
RuntimeMaxSec=604800

Also I increased /etc/systemd/system.conf
