I'm trying to import the module dynamically but It's failing for no reason

 import('../Util/Cache/xxx.js').then((module) => {
      console.log('module', module);
    })

above one is working.

const path = `../Util/Cache/${fileName}`;
    import(path).then((module) => {
      console.log('module', module);
    })

This one is not working.

fileName is xxx.js
