What is the current behavior? I have created a simple custom plugin just a logo , now when I drag and drop to canvas I get the following error Cannot read properties of undefined (reading ‘uploadFile’)

If is necessary to execute some code in order to reproduce the bug, paste it here below:

import React, { useState, useEffect } from "react";
import { useDispatch } from "react-redux";
import grapesjs from "grapesjs";
import block from "grapesjs-blocks-basic";

const Editor = () => {
  const [editor, setEditor] = useState();
  const dispatch = useDispatch();

  //custom logo plugin
  function pageLogo(editor) {
    editor.BlockManager.add("logo", {
      label: `<div className="gjs-block-label"><img src="https://i.ibb.co/nL2Q7WN/logo.png"></div>`,
      content: `<span><img src="https://i.ibb.co/nL2Q7WN/logo.png" /></span>`,
      category: {
        id: "logo",
        label: "Logo",
        open: true
      }
    });
  }

  useEffect(() => {
    const editor = grapesjs.init({
      container: "#editor",
      storageManager: false,
      blockManager: true,
      plugins: [pageLogo]
    });

    setEditor(editor);
  }, [dispatch]);

  return (
    <>
      <div className="ModalVideos"></div>
      <div id="editor"></div>
    </>
  );
};

export default Editor;

@omergr8 I see no issues on the official demo, so if you believe the problem is still there, please open a new issue with a reproducible demo.
