Slate Plus (4.1.0 beta1) strange VPN Dashboard error message

I get the following every time I go to the VPN Dashboard:

“Unknown error occurred. Please check the network environment or reboot the device.“

I do not notice any issue. And the VPN (WG client) seems to be working well. I see the following in the nginx log which seems related:

2022/10/05 21:00:46 [error] 4455#0: *555 lua entry thread aborted: runtime error: /usr/lib/oui-httpd/rpc/vpn-policy:77: bad argument #2 to 'tonumber' (integer expected, got string)
stack traceback:

This is an upgrade from the previous 4.0.0 keeping settings.

Maybe just reset the firmware and the message will go away.

It doesn’t bother me at all. But if you’d like to debug it I can provide information. Otherwise, I’ll reset it at some point, yes.
