Hello,  
I have used this node before without issue, however when I run it in the latest docker container I am getting this error message. DataError: The Data Path can't be empty. If I test it outside a docker it works fine, but soon as it is in a docker container the error message appears.  
Here is the example flow I have been using.

```auto
[
    {
        "id": "50cbab180f96f2ec",
        "type": "DataIn",

                "b534ad217423053c"
            ]
        ]
    },
    {
        "id": "668fc139d5107d1c",
        "type": "debug",
        "z": "54e00243c63a0667",
        "name": "debug 2",
        "active": true,
        "tosidebar": true,
        "console": false,
        "tostatus": true,
        "complete": "payload",
        "targetType": "msg",
        "statusVal": "payload",
        "statusType": "auto",
        "x": 1100,
        "y": 780,
        "wires": []
    },
    {
        "id": "dd241ba0efa3c601",
        "type": "json-db-collection",
        "name": "",
        "collection": "workplace",
        "save": true
    }
]

```

I thought this could be a permission issue so I did a chmod 777 to the JsonDB folder and file that was created, but still no luck. Does anyone have any ideas as to why this flow works on a stand alone version but not in a docker container?  
Thanks

Well, I tried in docker and it failed.  
But so did the example delivered with it, too.

The node has not been updated in 6 years and most of it is way older...

I guess the node simply is broken.

Thanks for testing it out man, I tried what looks to be another clone and it looks to work. json-db-node-red So if anyone else has this issue just do not use that repo and use this one.
