I believe this problem was introduced in 3.5.0 in this commit: 1ff9e16

If I forcibly downgrade to version 3.4.13, the type error goes away.

Even though this package claims that it supports any React version in its peer dependencies, it's using a very new version of @types/react, which works only with React 18. We're using React 17 in our project, so that's why we're seeing this error. Seems like either the version of @types/react should be downgraded/reverted, or the peer dependencies should be updated to reflect reality.

It happen because this changed.

I'm not sure if this can help but you might try to add this in your package.json.

  "resolutions": {
    "@types/react": "^18.2.12"
  }
