body: {
   "product": {
      "title": "Naga Custom Freestyle 0077",
      "body_html": "**Good suncream!**",
      "vendor": "acegym",
      "product_type": "Suncream",
      "product_tags": [
          "Barnes & Noble 1",
          "Big Air 2",
          "John's Fav 3"
      ]
    }
}

This is the URL (method: “POST”)

const response = await fetch(`https://${api_key}:${admin_api_access_token}@${shop_name}.myshopify.com/admin/api/${api_version}/${api_name}.json`, {
    method,
    body
  });

The same request working in Postman but when I do it in NodeJs it is throwing this error.

{"errors":{"product":"Required parameter missing or invalid"}}

Can someone help me?

Thank you
