The stack trace pointed to:
/opt/librenms/app/Console/Commands/PortTune.php
where the code executes:
Rrd::tune('port', $rrdfile, $port->ifSpeed);
while the target method is defined as:
public function tune(string $type, RrdPath $rrd, int $max): bool
It seams that the problem is associated with the interfces that does not have ifSpeed, and return NULL
MariaDB [librenms]> SELECT
-> d.hostname,
-> p.port_id,
-> p.ifName,
-> p.ifDescr,
-> p.ifSpeed
-> FROM ports p
-> JOIN devices d ON d.device_id=p.device_id
-> WHERE p.ifType='ethernetCsmacd'
-> AND p.ifSpeed IS NULL
-> LIMIT 100;

So I modified this file /opt/librenms/app/Console/Commands/PortTune.php and changed the code.
Original:
Rrd::tune('port', $rrdfile, $port->ifSpeed);
Modified:
if ($port->ifSpeed !== null && $port->ifSpeed > 0) {
Rrd::tune('port', $rrdfile, (int) $port->ifSpeed);
}
And after the code modification, it started working again
