Hi @timdows , I've tried to solve this for two days by now but with no luck.

Hope you can help since I can't really see where the problem with position 5 is.

From console log I have this error:

This is the config array:

        {
            module: 'MMM-JsonTable',
            position: 'top_right',
            header: 'Dati ultima corsa',
            config: {
                    url: 'http://192.168.1.50/home/pi/MagicMirror/modules/MMM-JsonTable/prova.json',
                    arrayName: "items",
                    tryFormatDate: true
                    }

While this is the JSON content (UTF encoded, no BOM characters):

{
    "items": [
        {
            "name":"Data",
            "value":"20/9/20"
        },
        {
            "name":"Distanza",
            "value":"10 Km"
        },
        {
            "name":"Durata",
            "value":"0:52:30"
        },
        {
            "name":"Passo",
            "value":"0:5:15"
        },
        {
            "name":"VDOT",
            "value":"38"
        }
        ]
}

Thank you in advance for your precious support.

Good check already on BOM and UTF, as the stack trace indicates the issue is in

var json = JSON.parse(body);

Can you supply the output for some vars over there by adding console.log('debug', error, response, body); on line 13 https://github.com/timdows/MMM-JsonTable/blob/master/node_helper.js#L13

Sure, here it is the console log:

Wait, I just see your url

http://192.168.1.50/home/pi/MagicMirror/modules/MMM-JsonTable/prova.json

Is this really working? Can you supply the raw output (show it in dev console of a broswer)?

What if you supply the following configuration

module: 'MMM-JsonTable',
position: 'top_right',
config: {
  url: 'https://jsonplaceholder.typicode.com/users',
  keepColumns: ['name', 'username']
}
aurely89 commented 3 years ago

Hi @timdows, I've had the same problem with the JSON file on a NAS or on a cloud drive.

I've tried with the config you've sent and the module still displays 'Awaiting json data' but I see a different error on the console log:

Of course try that config with the original node_helper.js file

aurely89 commented 3 years ago

Oh, sure. It is correctly working now, so I guess it was a reachability problem.

Thank you very much @timdows!
