[Solved]-How can I fix the error #17 "The requested series type does not exist" error when trying to display a highcharts graph in Vue.js?-Highcharts

OK, so it was in the API reference:

series.item

An item series. If the type option is not specified, it is inherited from chart.type.

(...)

Requires

• modules/item-series

The hint of the module item-series helps us find the issue for Vue.js: it needs to import item from 'highcharts/modules/item-series'; and then register it:

import HighchartsVue from 'highcharts-vue';
import highchartsMore from 'highcharts/highcharts-more';
import item from 'highcharts/modules/item-series';

import Vue from "vue";


Vue.use(HighchartsVue);
item(Highcharts);

The same solution (with its corresponding module) should work for other graphs and you can find the list of all modules in https://code.highcharts.com/.
