I can't seem to create a thumbnail from a video file in javascript. I keep getting the following error:

ChildProcessError: `/workspace/node_modules/@ffmpeg-installer/linux-x64/ffmpeg -ss 0 -I valid-video-link -f image2 -vframes 1 -vf scale=10:10 -update 1 /tmp/thumbnails/TTT1633248087A995.jpg` failed with code 1`

Here is my code:

const spawn = require('child-process-promise').spawn;
const ffmpegPath = require('@ffmpeg-installer/ffmpeg').path;
const promise = spawn(ffmpegPath, ['-ss', '0', '-i', fileUrl, '-f', 'image2', '-vframes', '1', '-vf', `scale=10:10`, `-update`, `1`, tempLocalThumbnailFile]);

The promise comes up undefined. Any help would be appreciated!
