This morning I suddenly got the following error when I didn’t make any changes. Please help me to fix that.

Error page:

ports-of-device
ports-of-device1172×382 45.5 KB

librenms.log:

Trying to access array offset on value of type null {“view”:{“view”:“/opt/librenms/resources/views/device/index.blade.php”,“data”:},“userId”:43,“exception”:“[object] (Spatie\LaravelIgnition\Exceptions\ViewException(code: 0): Trying to access array offset on value of type null at /opt/librenms/app/Http/Controllers/Device/Tabs/NetflowController.php:39)

update to latest codebase with ./daily.sh . this fixed it for me.

Hello. Same problem with ports

But link:

  • librenms/device/XX/ports isn’t work
  • librenms/device/XX/ports/basic - work

For different devices errors gone after updating port settings in the preference for the device librenms/device/XX/edit/section=ports by pressing “Save Toggles”
For juniper devices, it doesn’t help

Thanks
