Highchart is not showing in heroku, but works in local environment - ruby-on-rails

Question

I am using ember-highcharts in my app. I tested in my localhost and it is working fine, the graphic is showing in the screen.
I deployed my application in heroku, and try to show the graphic but the error below appears:
Uncaught TypeError: Cannot read property 'parentGroup' of undefined
at object.setState (highcharts.src.js:33606)
at SVGGElement. (highcharts.src.js:33080)
Here is my code:
{{#if question.chartData}}
{{high-charts content=question.chartData chartOptions=chartOptions}}
{{else}}
<div class="modal__warning">Dados insuficientes</div>
{{/if}}
chartOptions: {
chart: {
plotBackgroundColor: null,
plotBorderWidth: 0,
plotShadow: false
},
title: {
text: null
},
tooltip: {
pointFormat: '<b>{point.percentage:.1f}%</b>'
},
plotOptions: {
pie: {
colors: [
'#60E0A1',
'#F19692',
'#d5d5d5',
'#68599D',
'#A69BC5'
],
dataLabels: {
enabled: false
},
size: '100%',
showInLegend: true,
startAngle: -90,
endAngle: 90,
center: ['50%', '100%']
}
},
yAxis: {
title: {
text: null
}
}
}
Does anyone know what the problem could be? Just remember that in my local machine is working fine!
Thanks in advance :)

Answer 1

I've discovered the issue. What happened is that the data that I was sending to Highcharts was using an incorrect format.
I am plotting a pie chart, and the data should be in the format below:
[ ["test", 10.0], ["test2", 85.0], ["test3", 5.0] ]
And I was sending the data like this:
{ {"test", 10.0}, {"test2", 85.0}, {"test3", 5.0} }
For some reason this caused the problem mentioned.
