Usage with registerContentScripts

[rendomnet]

What should I specify in the 'js' field? Should it be relative to my root directory? Is it necessary for 'contentScript.js' to reside in the public directory? Could someone kindly provide an explanation?"

          chrome.scripting.registerContentScripts([
            {
              id: 'contentScript',
              matches: ['*://*/*'],
              js: ['/contentScript.js'],
            },
          ]);

I got this error

Uncaught (in promise) Error: Could not load javascript 'contentScript.js' for content script.
