## TL;DR

For "ReferenceError: Can't find variable: React": upgrade to @nhost/nextjs 1.13.25 or later, the package build emitted React.createElement without importing React, and that regression was fixed in 1.13.25. A fixed build was released in @nhost/nextjs 1.13.25.

```

## Steps

1. Upgrade to @nhost/nextjs 1.13.25 or later, the package build emitted React.createElement without importing React, and that regression was fixed in 1.13.25. If you must stay on 1.13.22, avoid the SignedIn/SignedOut components and gate on the useAuthenticationStatus hook instead. Source: https://github.com/nhost/nhost/issues/1914
