I believe this problem was introduced in 3.5.0 in this commit: https://github.com/react-component/virtual-list/commit/1ff9e16db54e2bdc03669c7cd330b8ed8bc60ee5

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. https://github.com/DefinitelyTyped/DefinitelyTyped/commit/f1b25591890978a92c610ce575ea2ba2bbde6a89

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"
  }
