[linonetwo]

Description

I'm trying to fetch a local resource using Fetch API

const mjsContent = await fetch(mjsPluginUrl, {
        headers: {
          // doing cors request to mjs file
          'Access-Control-Allow-Origin': '*',
        },
      }).then(async response => await response.text());

get
