Error Can't resolve 'fs'

Hello everyone, I'm facing an error integrating Casbin accessControlProvider here is the code for accessControlProvider I followed from the documentation

 accessControlProvider={{
                can: async ({ resource, action }) => {
                  const enforcer = await newEnforcer(model, adapter);
                  const can = await enforcer.enforce('admin', resource, action);

                  return { can };
                },
              }}

And its showing Can't resolve 'fs'

Hey @franzdev! I'm the kapa.ai support bot. I've searched through the docs to try to answer your question. :wave:

---------------------- To resolve the "Can't resolve 'fs'" error when integrating Casbin with refine, you need to configure polyfills for casbin to work in a browser environment. You can use react-app-rewired to override some of the configurations of your app. Follow these steps: 1. Add react-app-rewired to your project:

yarn add react-app-rewired

yarn add react-app-rewired

2. Update the scripts in your package.json:

"scripts": {
  "start": "react-app-rewired start",
  "build": "react-app-rewired build",
  "eject": "react-scripts eject",
  "refine": "refine"
},

"scripts": {
  "start": "react-app-rewired start",
  "build": "react-app-rewired build",
  "eject": "react-scripts eject",
  "refine": "refine"
},

3. Add the following packages:

yarn add assert buffer crypto-browserify stream-browserify
yarn add -D https-browserify os-browserify path stream-http

yarn add assert buffer crypto-browserify stream-browserify
yarn add -D https-browserify os-browserify path stream-http

4. Include the config-overrides.js file in the root of your app folder. You can find the file here (https://github.com/anewman15/refine/blob/pixels-admin/examples/pixels-admin/config-overrides.js). After completing these steps, the error should be resolved. For more information, refer to the Browser Fallbacks for Casbin section (https://refine.dev/blog/refine-pixels-6/#browser-fallbacks-for-casbin) in the refine blog. ----------------------
