According to the docs the faceapi.fetchImage accepts an path, not filecontent/buffer.

So, instead of doing var image = fs.readFileSync(path) you should just do:

try{
    const image = await faceapi.fetchImage(path)
} catch (e){
    console.log("Error e "+e)
}

Note that in your example code `path` would only be an online resource (or one served by your local server), not a local file on the HD. – Boris Yakubchik Jan 20 '20 at 17:59

fetchImage will not work with a local resource, because "fetch" is for the web.

You'll want to npm install canvas and then simply do this:

const canvas = require('canvas');
faceapi.env.monkeyPatch({ Canvas, Image })
const img = await canvas.loadImage('./img.jpg');
const detections = await faceapi.detectSingleFace(img);
