Zeus and sandbox start up error

[General_Cookie]

Getting a error when the server is trying to start up zeus and sandbox:
[error] [string "sandbox/common/file.lua"] :2: attempt to index a nil value (global 'io')
[error] [string "zeus/server/libs/date.lua"] :46: attempt to index a nil value (local 'os')

Did you enable sandbox? (https://dev.playonset.com/wiki/server_config) This will disable io and os namespaces.

"plugins": [
"mariadb",
"ini-plugin"
],
"packages": [
"packagemanager",
"zeus",
"default",
"elevator",
"freeroam",
"sandbox"
],

something like this then?

No, I mean the "sandbox" setting (see the server_config page). When you enable this setting the io and os namespaces are not available.
