Based on the provided code and error messages, here’s a step-by-step guide to help you resolve the issue:

1. Upgrade React and @xyflow/react:

   • The error message suggests that there’s an issue with react/jsx-runtime. You’re currently using @xyflow/react version 12.3.5, which might not be compatible with the new React version.

   • To fix this, you can try upgrading to a newer version of @xyflow/react. However, since React 18 has been released, it’s recommended to upgrade to React 18 instead.

     You can use the following commands to install and configure React:

npm install react react-dom –save

        If you want to switch to React 18, use the following command:

        ```bash
npx create-react-app my-app --template typescript
cd my-app
npm install @xyflow/react@latest

2. Update webpack.config.js:

   • The error message also mentions that there’s a module not found issue in the @xyflow/react package.

   • You’ve already added some aliases to resolve in your webpack.config.js. However, this might not be enough to resolve the issue.

     To fix this, you can try updating your webpack.config.js with the following configuration:

module.exports = { //… other configurations … resolve: { alias: { ‘react/jsx-runtime’: path.resolve(__dirname, ‘./node_modules/react/jsx runtime/index.js’), }, }, };

3.  **Check for conflicts with React R and `@xyflow/react`**:

    *   Sometimes, issues arise due to compatibility problems between different packages.
    *   Try updating your `R/reactflow.R` file to the latest version using:

        ```r
devtools::install(quick = TRUE)

4. Clean and rebuild the project:

   • After making changes to your webpack.config.js, clean the project by running:

yarn cache clean yarn install

    *   Then, try rebuilding the project again using:
        ```bash
shiny::runApp()

5. Consider a full reset:

   • If none of the above steps resolve the issue, consider starting from scratch.
   • Try deleting your node_modules directory and running:

yarn install yarn run webpack

    *   Then, rebuild the project using:
        ```bash
shiny::runApp()
