How to make video or audio optional in transcoder api?

Question

I am currently converting a video. Uploaded to cloud storage using a signed URL, using Transcoder API and transcoding a video larger than 5 seconds. But when video or audio is missing the job failed. How do I make video or audio optional for my job?

My Current Code:

job.config = transcoder_v1.types.JobConfig(
        elementary_streams=[
            transcoder_v1.types.ElementaryStream(
                key="video-stream0",
                video_stream=transcoder_v1.types.VideoStream(
                    h264=transcoder_v1.types.VideoStream.H264CodecSettings(
                        bitrate_bps=550000,
                        frame_rate=60,
                    ),
                ),
            ),
            transcoder_v1.types.ElementaryStream(
                key="video-stream1",
                video_stream=transcoder_v1.types.VideoStream(
                    h264=transcoder_v1.types.VideoStream.H264CodecSettings(
                        bitrate_bps=2500000,
                        frame_rate=60,
                    ),
                ),

            ),
            transcoder_v1.types.ElementaryStream(
                key="audio-stream0",
                audio_stream=transcoder_v1.types.AudioStream(
                    codec="aac", bitrate_bps=64000
                ),
            ),
        ],
        mux_streams=[
            transcoder_v1.types.MuxStream(
                key="sd",
                container="ts",
                elementary_streams=["video-stream0", "audio-stream0"],
            ),
            transcoder_v1.types.MuxStream(
                key="hd",
                container="ts",
                elementary_streams=["video-stream1", "audio-stream0"],
            ),
            
        ],
        manifests=[
            transcoder_v1.types.Manifest(
                type="HLS",
                mux_streams=["sd", "hd"],
            ),
        ],
    )

Error message:
No Audio:

\atom atom0 does not have any inputs (input0) with an audio track

No Video:
