Video encoded with no sound

There is a job template I use to encode video.

The origin template you can see here: https://github.com/aws-solutions/video-on-demand-on-aws/blob/main/source/custom-resource/lib/mediaconvert/templates/1080p_avc_aac_16x9_qvbr_no_preset.json I changed the variable bitrate to static, and the HV1 codec was replaced with LC.
I encode two videos with pretty similar definitions. Here they are:

One of them encoded successfully and played correctly. The second one is without any sound. There are links to play them, and it seems like the first one doesn't contain a sound stream.

I don't see any errors in my AWS MediaConvert job. Can somebody help with indicating the issue? Is there any workaround to handle it?
