Object(...) is not a function at eval (vue-codemirror.esm.js:7:1)

[isaacfink]

Describe the bug

I have the following component

<template>
  <Codemirror
    v-model="code"
    placeholder="Code goes here..."
    :style="{ height: '400px' }"
    :autofocus="true"
    :indent-with-tab="true"
    :tab-size="2"
    :extensions="extensions"
    @ready="handleReady"
    @change="console.log($event)"
    @focus="console.log('focus', $event)"
    @blur="console.log('blur', $event)"
  />
</template>

<script lang="ts">
  import Vue from 'vue'
  import Component from 'vue-class-component'
  import Icon from '../Icon.vue'
  import { Codemirror } from 'vue-codemirror'
  import { sql } from '@codemirror/lang-sql'
  import { oneDark } from '@codemirror/theme-one-dark'

  @Component({
    components: { Icon, Codemirror },
    props: {
      label: {
        type: String,
        default: ''
      },
      error: {
        type: Boolean,
        default: false
      },
      value: {
        type: String,
        default: ''
      }
    },

    mounted () {
      console.log('mmounted code editor')
    }
  })
  export default class TextareaCode extends Vue {
    code: string = ''
    event:string = ''
    extensions = [sql(), oneDark]
    handleReady = () => {}
  }
</script>

But I am getting the following error in the console

Object(...) is not a function
    at eval (vue-codemirror.esm.js:7:1)

I am not sure where to even look, is this a bug or is there something wrong with my implementation?

Reproduction

just the code above
