VM1050:1 Uncaught ReferenceError: Highcharts is not defined

[byphone]

Hi,

I have two pjax container, each one being a destination for a graphic. The reload of the containers is managed by a js like that
$.pjax.reload({url: '/dashboard/dashboard/graph-calls', container: '#dashboard-graphcalls', data: {dashboardperiod: '1580515200'}, async: true, push: false, replace: false, type: 'POST'});

$.pjax.reload({url: '/dashboard/dashboard/graph-mins', container: '#dashboard-graphmins', data: {dashboardperiod: '1580515200'}, async: true, push: false, replace: false, type: 'POST'});

i write the js code to be sure that second reload is executed when first is completed, to avoid simultaneous pjax request.

The first reload is a success, the second throw a js exception :
VM1050:1 Uncaught ReferenceError: Highcharts is not defined

at next (jquery.pjax.js:833)
at HTMLScriptElement.cb (jquery.pjax.js:813)
at next (jquery.pjax.js:833)

After this error, i write manually in the chrome console the command to reload the second pjax container , it's ok.

Idea ?
