Pose estimation device linkage fails for ndx_franklab_novela.CameraDevice

[pauladkisson]

After writing, the PoseEstimation.devices field shows up as None when linked to a CameraDevice from ndx_franklab_novela. See minimal example below.

        model="model",
        lens="lens",
        camera_name="camera_name",
    )
    nwbfile.add_device(camera_device)
    device = nwbfile.devices["Device"]

    pose_estimation = PoseEstimation(
        name="PoseEstimation",
        devices=[device],
    )
    nwbfile.create_processing_module(
        name="behavior",
        description="behavior",
    )
    nwbfile.processing["behavior"].add(pose_estimation)
