**"Next.js + Wix Headless: ricos-viewer React 19 Compatibility Issue"**

Question:
“Next.js + Wix Headless: ricos-viewer React 19 Compatibility Issue”
I am using ricos-viewer along with wix-rich-content-plugin-divider, wix-rich-content-plugin-headings, and wix-rich-content-plugin-image in my Next.js application. However, I am facing a runtime error related to the legacy context API in React 19.

Code Implementation

Component Code:

"use client";
import React from "react";
import { DraftContent, RicosViewer } from "ricos-viewer";
import { pluginDivider } from "wix-rich-content-plugin-divider/viewer";
import { pluginHeadings } from "wix-rich-content-plugin-headings/viewer";
import { pluginImage } from "wix-rich-content-plugin-image/viewer";

const plugins = [
  pluginDivider({
    size: "medium",
  }),
  pluginImage(),
  pluginHeadings(),
];

const RichContentViewer = ({ content }: { content: DraftContent }) => {
  return (
    <div>
      <RicosViewer content={content} plugins={plugins} />
    </div>
  );
};

export default RichContentViewer;

Component Render

import { toDraft } from "ricos-content/libs/toDraft";
<RichContentViewer content={toDraft(bannerData?.title1)} />

Error Message:
I18nextProvider uses the legacy childContextTypes API which was removed in React 19.
Use React.createContext() instead. (React 19 Upgrade Guide – React)
TypeError: Cannot read properties of undefined (reading ‘options’)
at new Translate (translate.js:51:135)

Steps Taken:
I have ensured that my dependencies are up to date.
Tried wrapping the component in a different provider but still faced the issue.

Is there a way to replace I18nextProvider with a React.createContext implementation within ricos-viewer?
Could this issue be due to a dependency conflict? How can I debug this further?

It looks like @wix/ricos doesn’t support React 19. Is there any kind of timeline on when that support might be added, or any alternatives in the meantime?
