Domoticz error with lua

Hello,
Since last version of domoticz (in docker latest release) 4.11464 some people like me have a lot of errors in log like this:
` 2019-11-17 18:52:01.747 Error: EventSystem: in /var/lib/domoticz/dzVents/runtime/dzVents.lua: …oticz/dzVents/runtime/device-adapters/generic_device.lua:203: attempt to call field ‘tointeger’ (a nil value)

the last updated container is 13 days ago.
Is this a common problem?

thanks a lot

News of this error.
Its related with a migration of lua version.

To fix it in a easy way i make this:
edit this file in docker:
/var/lib/domoticz/dzVents/runtime/device-adapters/generic_device.lua

and change the math.tointeger with a math.floor in the 203 line.

All errors disapears.

thanks!
