'-help filter=convolve' never resolve the promise

Describe the bug -help filter=convolve never resolve the promise.

To Reproduce

const ffmpeg = createFFmpeg();

await ffmpeg.load();

await ffmpeg.run("-hide_banner", "-help", 'filter=convolve');

console.log('done');

Expected behavior resolve after this command finished
