Hey @awwdam I’m also having an issue with the customerUpdate endpoint when trying to update an address. If i send all empty strings it works and updates the default address of the Customer, but once I try to send interpolated data, the mutation runs successfully, however it does not update the Customer object and returns an empty array for addresses

{
    input: {
      id: `gid://shopify/Customer/${data.id}`,      
      addresses: [
        {
          address1: `${data.address1}`,
          address2: `${data.address2}`,
          city: `${data.city}`,
          company: "",
          countryCode: `${data.country_code}`,
          firstName: `${data.first_name}`,
          lastName: `${data.last_name}`,
          provinceCode: `${data.province_code}`,
          zip: `${data.zip}`
        }
      ]
    }
  }

response of the customer object:

{
  id: 'gid://shopify/Customer/CUSTOMER_ID',
  firstName: 'firstName',
  lastName: 'lastName',
  defaultAddress: null,
  addresses: []
}
