@LeeLenaleee this is line graph component code. there is a problem in linechartgenerator. when i am calling this component i got that error

<template>
  <LineChartGenerator
    :chart-options="chartOptions"
    :chart-data="chartData"
    :chart-id="chartId"
    :dataset-id-key="datasetIdKey"
    :plugins="plugins"
    :css-classes="cssClasses"
    :styles="styles"
    :width="width"
    :height="height"
	  :key="indexKey"
  />
  
</template>


<script>
import { Line as LineChartGenerator } from 'vue-chartjs/legacy'

import {
  Chart as ChartJS,
  Title,
  Tooltip,
  Legend,
  LineElement,
  LinearScale,
  CategoryScale,
  PointElement
} from 'chart.js'

ChartJS.register(
  Title,
  Tooltip,
  Legend,
  LineElement,
  LinearScale,
  CategoryScale,
  PointElement
)
