For the meanwhile, I've removed lang="ts" from my <script> tag in the .vue component file

I think the issue is on the line :

const canvas = <HTMLCanvasElement> document.getElementById('myChart');

because of the case, you can use the as syntax to avoid the lint issue

const canvas = document.getElementById('myChart') as HTMLCanvasElement;

If you still have an issue check you .eslint.*, mine is like this:

module.exports = {
  root: true,
  env: {
    node: true,
  },
  parser: 'vue-eslint-parser',
  parserOptions: {
    parser: '@typescript-eslint/parser',
  },
  plugins: ['vue','typescript'],
  extends: [
    'eslint:recommended',
    'plugin:@typescript-eslint/eslint-recommended',
    'plugin:@typescript-eslint/recommended',
    'plugin:vue/essential',
    '@vue/typescript',
  ],
}
