Cannot read properties of null (reading 'useReducer')

Hi all,

Thanks for your open libraries, loving working with Solara so far!

I just discovered ipyreact also and I'm trying to see how easy it is for using react libraries with.

Currently trying to demo the react-pdf library and have overcome earlier errors but I'm now getting "Cannot read properties of null (reading 'useReducer')"

My code is the following:

import ipyreact

ipyreact.Widget(
    _esm="""
    import { Document, Page, pdfjs } from "https://esm.sh/react-pdf";
    import * as React from "react";


    pdfjs.GlobalWorkerOptions.workerSrc = `//unpkg.com/pdfjs-dist@${pdfjs.version}/build/pdf.worker.min.js`;

    export default function MyApp() {

      return (
        <div>
          <Document file="https://mozilla.github.io/pdf.js/web/compressed.tracemonkey-pldi-09.pdf" >
          </Document>
        </div>
      );
    };
    """
)

Hoping you might be able to advise.

Thanks a lot

Start by reproducing the embedded _esm example with react-pdf in ipyreact and inspect the reported useReducer error. Compare the Document and Page imports with a minimal React component to isolate the failing integration. Done means identifying a supported configuration or documenting the incompatibility and required project change.
