get_environment method returns "not implemented"

[theunpleasantowl]

The README.md says that the get_environment method is supported but querying my switches, I get a response saying that it's not implemented:

HTTP 200 OK
Allow: GET, HEAD, OPTIONS
Content-Type: application/json
Vary: Accept

{
    "get_environment": {
        "error": "Method get_environment not implemented for NAPALM driver <class 'napalm_dellos10.dellos10.DellOS10Driver'>"
    }
}

Here is one of my switches (though I have several with the same problem):

     "vendor": "Dell",
        "os_version": "10.5.2.7",
        "model": "S3048-ON"

I am using the latest napalm-dellos10 package from PyPi
