Problem description:

With the code below I am getting this error: TypeError: Cannot read properties of undefined (reading 'elements')

Relevant code:

          <mesh position={[0, -1.5, 0]} rotation={[-Math.PI / 2, 0, 0]}>
              <planeGeometry args={[50, 50]} />
              <MeshReflectorMaterial
                  blur={[400, 400]}
                  resolution={1024}
                  mixBlur={1}
                  mixStrength={15}
