I deleted and re-created a Juniper MX device in Libre as I notice a few interfaces were not graphing properly and had funky MTU’s. Other than that everything was working fine (I did reuse the same hostnames during recreation). After the recreation I have a bunch of errors on graph and or no graphs at all. The error is not wrong. The files do not exist in the mentioned directory. Just a ton of port files are in that directory.
