CORS and 502 Bad Gateway Errors When Fetching from https://api.events.unlayer.com/usage

[MarkoPl08]

While integrating the react-email-editor component into my React application, I observed errors in the console related to CORS and a 502 Bad Gateway. Notably, I'm using only the basic functionalities of the editor and not making any explicit fetch requests to the problematic URL.

Error: Access to fetch at 'https://api.events.unlayer.com/usage' from origin 'https://editor.unlayer.com' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource.

502 Bad Gateway Error: POST https://api.events.unlayer.com/usage net::ERR_FAILED 502 (Bad Gateway)

Steps to reproduce:

1. Integrate react-email-editor into a React component as shown below.
2. Load the component in a browser.
3. Observe the console for the aforementioned errors. Expected behavior: The react-email-editor should be able to function without any CORS or 502 errors, especially when using basic functionalities.

Code Sample:

import React, { useRef } from 'react';
import EmailEditor, { EditorRef, EmailEditorProps } from 'react-email-editor';

const EmailEditorSample = () => {
  const emailEditorRef = useRef<EditorRef>(null);

  const exportHtml = () => {
    const unlayer = emailEditorRef.current?.editor;
    unlayer?.exportHtml((data) => {
      const { design, html } = data;
      console.log('exportHtml', html);
    });
  };

  const onReady: EmailEditorProps['onReady'] = (unlayer) => {
    // This can be where you load a design or handle other "onReady" tasks
  };

  return (
    <div>
      <h4>Email Editor Sample</h4>
      <EmailEditor ref={emailEditorRef} onReady={onReady} />
      <button onClick={exportHtml}>Export HTML</button>
    </div>
  );
};

export default EmailEditorSample;

@MarkoPl08 did you solved this error?

I also get this "502" error, but it seems to work anyway. Do you know how to remove this console error?

They fixed it in a patch shortly after my post so i am closing this issue.
