Material Tailwind - TypeError: Cannot read properties of null (reading 'useContext')

Question

I am making a client project using React with Typescript and using Material Tailwind UI - MT. But when using MT's components, I get a useContext error, it seems to be reported in MT's theme.js. I have tried everything but still can't fix it, does anyone know this error?

Error Message

Error Message 1

Warning: Invalid hook call. Hooks can only be called inside of the body of a function component. This could happen for one of the following reasons:
1. You might have mismatching versions of React and the renderer (such as React DOM)
2. You might be breaking the Rules of Hooks
3. You might have more than one copy of React in the same app
See https://reactjs.org/link/invalid-hook-call for tips about how to debug and fix this problem.

            <Outlet/>
        </div>

export default App;

I tried very hard to try everything like updating to the last version, downgrading the version but it didn't work. Hope to get help from everyone <3

Answer 1

+1 to what Abid says Just make sure you set the dependencies of node_modules/@material-tailwind/react in your package-lock.json .. that should work.

They should match the version of react and react-dom in your package.json

package-lock.json

"node_modules/@material-tailwind/react": {
  "version": "2.1.9",
  "resolved": "https://registry.npmjs.org/@material-tailwind/react/-/react-2.1.9.tgz",
  "dependencies": {
    ..
    "react": "18.3.1",
    "react-dom": "18.3.1",
  },
  "peerDependencies": {
    "react": "^16 || ^17 || ^18",
    "react-dom": "^16 || ^17 || ^18"
  }
