Error Facade.php on line 355 at cache/Port.php:31

We are having problems on our dashboard. The images of the graphs have stopped working and when we click on them we get an error message telling us to contact support.
Error-ID : 33cdbeac-34c6-4ea4-a94a-c43004ce8998
Checking the librenms.log the error that appears just when you click on it is the following:

[2025-01-23T11:24:48][ERROR] LibreNMS\Cache\Port::get(): Argument #1 ($port_id) must be of type int, string given, called in /opt/librenms/vendor/laravel/framework/src/Illuminate/Support/Facades/Facade.php on line 355 {"userId":48,"exception":"[object] (TypeError(code: 0): LibreNMS\\Cache\\Port::get(): Argument #1 ($port_id) must be of type int, string given, called in /opt/librenms/vendor/laravel/framework/src/Illuminate/Support/Facades/Facade.php on line 355 at /opt/librenms/LibreNMS/Cache/Port.php:31)"}

Broken widgets are of the type ‘manual ports’.

This is my validate.php:

I have identical problem:

Ditto. Seeing the same, but only on certain graphs on the dashboards. Eding and recreating the graphs fixed the issue it seems

In my case this solution does not work.
Thanks,

I noticed some extra bank space in my port config. that fixed it on another instance of mine

Ok. I have the solution.
This must be a bug.
When you create a “manual port” widget in Ports section automatically adds a ghost item.
ejemplo1
You have to delete thie item for it to work.
When you try to edit the element again, the ghost element appears again.

Okay, it’s worked. But I don’t guess it’s the best practice for this issue. Something happened after the update on January 21th. Probably the dev’s will never fix it, and in the future we need to exclude this ghost item again. I have a lot’s of manual ports in Dashboard. I really wish they fixed it to avoid future issues.
