HTTP API - no parameters.firmware when also requesting empty group

We are trying to use the API for monitoring cameras.

NX version: 5.0.0.36634

When we do a GET request to /devices with `parameters.firmware` as well as `parameters.customGroupId` with `_keepDefault=true`, when we don't have a camera in a custom group, the result parameters section is empty.

API call:
`/rest/v1/devices?_format=JSON&_with=id,name,mac,model,parameters.firmware,status,vendor,parameters.customGroupId&_keepDefault=true&_orderBy=name`

Result:
```

[
    {
        "id": "{3213cee7-5af9-bcc2-83a6-08e30432c34a}",
        "mac": "08-A1-89-FE-59-D1",
        "model": "I91BM",
        "name": "Back Yard",
        "parameters": {
            "customGroupId": "Back Yard",
            "firmware": "V5.5.111 build 201223"
        },
        "status": "Recording",
        "vendor": "HIKVISION"
    },
    {
        "id": "{e82eecc2-abab-c425-ac69-c501dfa8f66b}",
        "mac": "08-ED-ED-7D-F9-19",
        "model": "IPC-HDW2431TM-AS-S2",
        "name": "Front Cam",
        "parameters": {},
        "status": "Recording",
        "vendor": "Dahua"
    }
]
```

If `_keepDefault` is FALSE:

`/rest/v1/devices?_format=JSON&_with=id,name,mac,model,parameters.firmware,status,vendor,parameters.customGroupId&_keepDefault=false&_orderBy=name`
The result is:

```
[
    {
        "id": "{3213cee7-5af9-bcc2-83a6-08e30432c34a}",
        "mac": "08-A1-89-FE-59-D1",
        "model": "I91BM",
        "name": "Back Yard",
        "parameters": {
            "customGroupId": "Back Yard",
            "firmware": "V5.5.111 build 201223"
        },
        "status": "Recording",
        "vendor": "HIKVISION"
    },
    {
        "id": "{e82eecc2-abab-c425-ac69-c501dfa8f66b}",
        "mac": "08-ED-ED-7D-F9-19",
        "model": "IPC-HDW2431TM-AS-S2",
        "name": "Front Cam",
        "parameters": {
            "firmware": "2.800.0000000.14.R, Build Date 2020-02-29"
        },
        "status": "Recording",
        "vendor": "Dahua"
    }
]
```

Is this expected? Or a bug?

  Hi,

  It's a bug. It has been fixed in v5.1. You could check in Nx Meta v 5.1.0.36973 R5.

  Hi Andrey,
  
  Where can I obtain this version? I am unable to find it under myNetworkOptix Downloads.
  
  Also, is this a Nx Meta only fix and not yet present in Nx Witness VMS?
