Python version incompatibility in sharp package

Summary

I'm trying to use GitLab AutoDevOps Dependency scanning on my node.js project with npm. I have sharp package in my package.json, seems like it is python version incompatibility. When I remove sharp package, Installing dependencies works fine.

Steps to reproduce

Use sharp package from npm and run dependency checking

What is the current bug behavior?

Dependency checking job fails
