As you can see the error 'Video Failed to Transcode' is displayed

I see an index.m3u8 file created in the designated directory . This contains the following entries:

#EXTM3U
#EXT-X-VERSION:3
#EXT-X-STREAM-INF:BANDWIDTH=800000,RESOLUTION=640x360
360.m3u8
#EXT-X-STREAM-INF:BANDWIDTH=1400000,RESOLUTION=842x480
480.m3u8
#EXT-X-STREAM-INF:BANDWIDTH=2800000,RESOLUTION=1280x720
720.m3u8
#EXT-X-STREAM-INF:BANDWIDTH=5000000,RESOLUTION=1920x1080

The code that is producing this is:

ffmpeg(fromurl)
.format('mp4')
.size('640x?')
.videoCodec('libx264')
.aspect('16:9')
.on('error', (err, stdout, stderr) => {
console.error('An error occured during encoding', err.message);
console.error('stdout:', stdout);
console.error('stderr:', stderr);
})
.on("progress", (progress) => console.log('Here is progress', progress))
.on('end', async function() {
console.log('Finished processing');

                    const t = new Transcoder.Transcoder('/workarea/temp.mp4', '/workarea/transcoded', {showLogs: true});
                    try {
                          const hlsPath = await t.transcode();
                          console.log('Successfully Transcoded Video');

                          console.log('Files', getAllFiles('/workarea/'));

                          fs.unlink(fromurl, (err) => {
                                if (err) {
                                      console.log("failed to delete local image:"+err);
                                } else {
                                      console.log('successfully deleted ', fromurl);                                
                                }
                          });

                    } catch(e){
                          console.log('Something went wrong', e);

                          fs.unlink(fromurl, (err) => {
                                if (err) {
                                      console.log("failed to delete local image:"+err);
                                } else {
                                      console.log('successfully deleted ', fromurl);                                
                                }
                          });
                    }

This takes a video file and first converts to mp4 and then attempts to transcode as a second stage to m3u8.

Would appreciate your thoughts on what might be happening...
