Leaving this answer to my own question so others might also stumble over it with the same problem.
In case any script file is loaded asynchronously after the initial page has been loaded, the file name reported in the Console will point to the file that performed the loading of the resource. In my case I used JQuery's $.getScript()
method to handle the task:
translationInitHandler.initialise(function() {
store.commit('setTranslation', window.defaultTranslationHandler.getCatalogueTranslations());
$.getScript('../src/app/report-template/warning.app.js');
$.getScript('../src/app/report-template/list.app.js');
$.getScript('../src/app/report-template/authorize.app.js');
$.getScript('../src/app/report-template/edit-configure.app.js?3');
}, false);
Funny thing is that the mentioned line and column refer to the right position in the loaded script. In my case I had (in IE11's view) an invalid property in a Vue application that had been included:
window.createApp = new Vue({
el: '#create-view',
store, // triggers IE error
data: {
...
},
...
});
<script>
tags so I can't post this in a fiddle or pen.
