I was having the exact same issue
I saw this thread: https://forum.proxmox.com/threads/rrdc-update-errors.81150/#post-358895

Just letting you know this deletes the previous graph log data
I deleted the db directory from /var/lib/rrdcached/db
The restarted the rrdcached using systemd and that fixed the errors from popping up
The db files were all regenerated and everything is working as normal

The commands used:

rm -r /var/lib/rrdcached/db
systemctl restart rrdcached.service
