Issue with nextjs 15.2.4

[jszsj]

I'm building a scene using nextjs v15.2.4 and react 19 with react-nodetoy:

<mesh rotation={[-Math.PI / 2, 0, 0]} position={[0, 0.1, 0]}>
    <planeGeometry attach='geometry' args={[300, 400]} />
    <NodeToyMaterial data={waterShader} />
</mesh>

I got the error: Error: R3F: NodeToyMaterial is not part of the THREE namespace! ..., then I added this line:

extend({ NodeToyMaterial })

another error popped up: Error: target is not a constructor

Is the current version incompatible with the latest Next.js and React?

Did you find a solution? I've got the same.
Upgrade of react-three/fiber@alpha sadly did not solve the issue.
