Page refresh causes Lightbox【gantt.locale.labels .section_ Details = "details"】 is invalid

http://snippet.dhtmlx.com/5/4c0bc4ce4
In my Vue project, the Lightbox is valid when it is just set to. However, the page fails as soon as the page is refreshed, and the【gantt.locale.labels .section_ Details = “details”】changes to undefined!

The configuration takes effect when the Vue project code is updated.
But the browser page fails as soon as it is refreshed:

I’ve found out why. Only by putting<gantt.i18n.setLocale(“cn”)>before <gantt.locale.labels.section_taskName = “任务名称”>, can it take effect at the same time
