Bounds incorrectly calculates center to be (0,0,0) on first render

Problem description:

I am using CameraControls (from drei) to allow the user to switch between different views of a 3D model that is being loaded with the useFBX() hook. I'm noticing that the first time I call the setCamera function below, the center is being incorrectly calculated to be (0,0,0), even though the box.min and box.max values are being correctly calculated. The size property also seems to be wrong. The subsequent times the function is called, all values are correct.

As a workaround, I am using the min and max to calculate the center.

Relevant code:

    const bounds = useBounds()

    function setCamera() {
      console.log(bounds.getSize())
      const target = computeCameraTarget(
        activeCamera.position,
        activeCamera.rotation,
        calculateDistance(cameraPos, bounds.getSize().center),
      )
      cameraControlsRef.current.setLookAt(
        activeCamera.position.y,
        activeCamera.position.z,
        activeCamera.position.x,
        target.y,
        target.z,
        target.x,
        true,
      )
    }
