Hi guys,

Im trying to setup a flow that will pull down the version number of the installed Node-Red package and store the information within an Input\_text helper within Home Assistant.

The command I am running seems to gather the information I need however when it attempts to update the input\_text entity I get the following error:

```auto
Call-service error. extra keys not allowed @ data['0']

```

The error seems to suggest that there is a character this is not allowed however I can't see what that might be.

Does it make a difference if you strip the carriage return off the end of the version string?

Thank you for reply, I was wondering about that but I wasn't sure how I could do that? Any ideas?

This is the command I am running:

```auto
npm -g info node-red version

```

The low code way would be to add `-json` to your command and then add a json node directly after the exec node.  
Or use a function node and add

```auto
msg.payload = msg.payload.trim()
return msg;

```

You could use `npm -g info node-red version | tr -d '\n'`

Or a change node in NR

```auto
[
    {
        "id": "0afc0aec5e666a4a",
        "type": "change",
        "z": "5541fa9c09b4fce3",

            {
                "t": "set",
                "p": "payload",
                "pt": "msg",
                "to": "$substringBefore($$.payload, \"\\n\")",
                "tot": "jsonata"
            }
        ],
        "action": "",
        "property": "",
        "from": "",
        "to": "",
        "reg": false,
        "x": 609.2000122070312,
        "y": 332.20001220703125,
        "wires": [
            [
                "c1b0021ca796317f"
            ]
        ]
    }
]

JSONata has a $trim() function that will remove whitespace before and after

This worked perfectly, thank you!

```auto
npm -g info node-red version | tr -d '\n'

```

Generally drowning people can not wave.
