Shopify Admin API create customer has odd response

Question

I'm able to successfully pull orders via the Admin API. I now am creating a custom create account widget and am using the same fetch methodology I used for getting the orders but posting to create the customer. Here is the fetch call:

const shopifyUserQuery = `
  query {
    customer {
      first_name: ${values.firstName},
      last_name: ${values.lastName},
      email: ${values.email},
      verified_email: true,
      password: ${values.password}
      password_confirmation: ${values.password},
      send_email_welcome = false;
    }
  }
  `
  const shopifyUser = await fetch(process.env.SHOPIFY_ADMIN_API_URL, {
    'body': shopifyUserQuery,
    'method': 'post',
    'headers': {
      'X-Shopify-Access-Token': shopifyAdminAccessToken,
      'Content-Type': 'application/graphql',
    },
  }).then((res) => console.log(res))

Now, the response is really odd - no errors, nothing just an odd blend of content in a zipped file:

}

Again, this admin token key does work but even if there were scope or perm issues (I did double check that my app has customer read and write scope) I'd expect a better error. Any help is appreciated.

Query Operation in Shopify GraphQL are type of get request where you can only get the demanded query list.

To edit or update anything on store you need to use Mutation operations (admin api required)

mutation test {
  customerCreate(input: {firstName: "", lastName: "", phone: "", email: ""})
}

for more clarity please visit - Shopify GraphQL

In the image you can see how to add a mutation operation.
