Display json data

[jagtarsingh]

Hello,

I am trying to display the json data using mozaik-ext-json widget. But I do not see anything on the dashboard except "unknown". I configured the widget as below:

Installed mozaik-ext-json
--> npm install --save mozaik-ext-json

Registered json. Below is the console log when I run node app.js
--> info: registered API 'json' (mode: poll)

Added json file on the same server which is accessible through http://server IP/a.json

Content of a.json
{
type: 'json.data',
title: 'Title',
value: 'Hello'
}

In the config.js added below:

// clients configs
api: {
    json: {
        url: 'http://server IP/a.json'
    }


    // first dashboard
    {
        // 4 x 3 dashboard
        columns: 4,
        rows:    3,
        widgets: [
            {
                type:  'json.data',
                title: 'THIS IS A TITLE',
                value: '${obj1.value}',
                columns: 1, rows: 1,
                x: 1, y: 1
            },

The console log shows below info:

$ node app.js

The Jenkins builds are successfully displayed on the dashboard

Thanks in advance.
