Syntax for customerUpdate mutation using node.js and shopify-api-node

[epodietz]

I am new to GraphQL...I was able to do a customerUpdate mutation using the GraphQL playground, but when I try it in a node.js script (below) I get the following error: "Error updating customer: RequestError: Variable $input of type CustomerInput! was provided invalid value."

const Shopify = require('shopify-api-node');

const shopify = new Shopify({

    shopName: 'mystore.myshopify.com',

    accessToken:'xxx'

});

const updateCustomer = async () => {

    const query = `

        mutation customerUpdate($input: CustomerInput!) {

        customerUpdate(input: $input) {

            userErrors {

                field

                message

              }

            customer {

            id

            firstName

            lastName

          }

        }

    }

        `

const variables= {

    "input": {

        "id": 'gid://shopify/Customer/1018520244',

        "firstName": 'Frank',

        "lastName": 'Jones'

        }

};

      try {

          const response = await shopify.graphql(query);

          console.log(JSON.stringify(response, null, 2));

      } catch (error) {

          console.log('Error updating customer:', error);

      }

    }  

  updateCustomer();

Hey @epodietz 

Looks like you're not passing the variables. You can pass them as a second argument to shopify.graphql like this:

const response = await shopify.graphql(query, variables);

Thanks, Scott. Pretty obvious, in retrospect. Now to glue back those hairs that I pulled out...
