when i change the data-source the console prints some error.

This is the template code

<kendo-datasource
  :ref="'datasource'"
  :data="chart">
</kendo-datasource>
<kendo-stockchart
  :data-source-ref="'datasource'"
  :date-field="'date'"
  :category-axis-labels-rotation="'auto'"
  :navigator-series="navigatorSeries"
  :navigator-category-axis-labels-rotation="'auto'"
  :theme="'sass'">
    <kendo-chart-series-item
      :type="'line'"
      :field="'value'">
    </kendo-chart-series-item>
 </kendo-stockchart>

 

And this is the JS

export default {
  name: "RatingHistory",
  components: {
    StockChart,
    DataSource
  },
  data(){
    return{
      services:Object,
      historicData:[],
      fields: {
        date: { type: 'date' }
      },
      navigatorSeries: {
        type: 'area',
        field: 'value'
      }
    }
  },
  computed:{
    chart(){
      return this.historicData
    }
  },
  created(){
    this.services = new Services()
    this.fetchData()
  },
  methods:{
    async fetchData(){
      let result
      try {
        result = await this.services.getRatingHistory()
      } catch(e) {
        console.log("Error getting data--->", e)
      }
      if(result.successful && result.statusCode === 200){
        this.historicData = result.data
      }
    }
  }
};

 

The chart render as expected, but i always see this error.

 

any light on how to prevent it ?
