Integrating with vue-quill on Vue3 gives error.

<template>
  <section>
    <quill-editor
      theme="snow"
      toolbar="full"
      v-model:content="content"
      :options="options"
      :modules="modules"
    />
  </section>
</template>

<script>
import { QuillEditor } from "@vueup/vue-quill";
import BlotFormatter from "quill-blot-formatter";

export default {
  name: "QEditor",
  components: {QuillEditor},
  data() {
    return {
      content: {},
      options: {
        placeholder: "Create a story...",
      },
      modules: {
        name: "blotFormatter",
        module: BlotFormatter,
        options: {/* options */},
      },
    };
  },
};
</script>

This is my code to integrate quill-blot-formatter with vue-quill but I am getting this console error. I followed this reference: https://vueup.github.io/vue-quill/guide/modules.html#example

quill-blot-formatter.js:187 Uncaught (in promise) TypeError: Cannot read property 'className' of undefined
    at new BlotFormatter (quill-blot-formatter.js:187)

Am I missing something in configuration or is it really an issue?

Some additional info from my debugging: On putting breakpoints in quill-blot-formatter.js I found in this line, this.options = deepmerge(DefaultOptions, options, { arrayMerge: dontMerge }); DefaultOptions is not getting populated and coming as undefined for me.

I installed quill-blot-formatter using npm. The version I am using is: "quill-blot-formatter": "1.0.5"

do not use import BlotFormatter from ‘quill-blot-formatter’ use import BlotFormatter from ‘quill-blot-formatter/dist/BlotFormatter’;
