I am encountering an error when running a Lambda function that merges audio chunks into a single audio file using Python 3.10.

The error message is:
No such file or directory: 'ffmpeg'

`def create_combined_audio_from_chunks(sorted_objects_key_list: List) -> AudioSegment:
“””
Create a merged audio from audio chunks
“””

# Create an empty AudioSegment object to hold the combined audio
combined_audio = AudioSegment.empty()

for key in sorted_objects_key_list:
    try:
        file_content = get_s3_object_content(object_key=key)

        with tempfile.NamedTemporaryFile(delete=True) as temp_file:
            temp_file.write(file_content)
            temp_file.seek(0)

            sound = AudioSegment.from_file_using_temporary_files(temp_file)

        combined_audio += sound
        
    except Exception as e:
        print(e)

return combined_audio`
