Luaengine script error every minute spams the hostlog with 10´s of thousands of lines a day.

Environment:

• OS name: [e.g. Ubuntu]: Raspbian OS (Debian)
• OS version: [e.g. 18.04]: 12 / Bookworm
• Architecture: [e.g. amd64]: ARM64
• ntopng version/revision: [e.g. 5.1.211223]: 6.3.250213 and 6.3.250222

What happened:
Every minute the logs on my NtopNG embedded installs on Raspberry PI 4 and 5 hardware gets spammed with the following sequence:

How did you reproduce it?
It always present after updating to 6.3.xxx daily builds

Debug Information:

There is no point in pasting the journalctl log for ntopng here. It's justs hundreds of thousands of repeats of the reported lines above.
