Videoshow doesnt throw any errors or exception in heroku

Hello, First thank you for you amazing work. I like it a lot. But now that I've transfered it to heroku it doesnt run. I use this buildpack - . I couldnt run your buildpack that you recommend. But anyway I installed this buidlpack and I thought everything works fine but it doesnt throw any errors, it doesnt enter the "onstart" event nor "on end" event. This is my code:

videoshow(images, videoOptions)
	.save('video.mp4').on('start', ()=>{
		console.log('start');
	}).on('error', (err, stdout, stderr)=>{
		console.error('Error:', err)
		console.error('ffmpeg stderr:', stderr)
		console.error('ffmpeg stdout:', stdout)
	}).on('end', ()=>{
		console.log('end');
	})

And this is the ffmpeg flags:

--enable-gpl --enable-version3 --enable-static --disable-debug --disable-ffplay --disable-indev=sndio --disable-outdev=sndio --cc=gcc --enable-fontconfig --enable-frei0r --enable-gnutls --enable-gmp --enable-libgme --enable-gray --enable-libaom --enable-libfribidi --enable-libass --enable-libvmaf --enable-libfreetype --enable-libmp3lame --enable-libopencore-amrnb --enable-libopencore-amrwb --enable-libopenjpeg --enable-librubberband --enable-libsoxr --enable-libspeex --enable-libsrt --enable-libvorbis --enable-libopus --enable-libtheora --enable-libvidstab --enable-libvo-amrwbenc --enable-libvpx --enable-libwebp --enable-libx264 --enable-libx265 --enable-libxml2 --enable-libdav1d --enable-libxvid --enable-libzvbi --enable-libzimg

libswresample   4.  0.100 /  4.  0.100
libpostproc    56.  0.100 / 56.  0.100

I dont see any console.log('start') or console.error('Error:', err). What is the problem with heroku?

My images had the wrong extension. When I fixed my images everything was working.
