How to use an image present in the same folder as script.js for face recognition using face-api.js?

Question

The entire project environment is in replit. The link provides the source code: https://replit.com/@dnabanita7/Face-Recog#script.js . I am sending in the code:

const imgUrl = '/leonard.png' 
const img = await faceapi.fetchImage(imgUrl)

and passing img.src value to the detectSingleFace() function but I am getting an error:

string passed but couldn't resolve HTMLElement id
