Graph image contains errors

[gil.obradors]

Thanks and congratulations to all for this great project.

Unable to determine when it broke. I have applied two consecutive upgrades via docker pull, and maybe I lose something doing git pull from this installation - > Librenms docker

All great, no error on upgrading, only all graph now are broken.

Seems that poller is updating files correclty, rrd files seems good

checking rrd files

Any idea what’s happening?
Caching of graph…?
