I have been recently playing with Shopify App Development and i'm struggling with a graphql call to amend some text. The image below displays the call being made correctly in the shopify GraphQL app which is where I test it.

However when I attempt to make this same call from the react component I get the following error

Unhandled Runtime Error
Error: GraphQL error: Field 'metafieldsSet' doesn't exist on type 'Mutation'
GraphQL error: Variable $metafields is declared by metafieldsSet but not used

Here is the react component in which I try and update the metafield

import React, { useState } from 'react';
import gql from 'graphql-tag';
import { Mutation } from 'react-apollo';
import { Layout, Button, Banner, Toast, Stack, Frame } from '@shopify/polaris';
import { Context } from '@shopify/app-bridge-react';
// GraphQL mutation that updates the prices of products
const UPDATE_TEXT = gql`mutation metafieldsSet($metafields: [MetafieldsSetInput!]!) {
    metafieldsSet(metafields: $metafields) {
      metafields {
        value
        id
        key
        ownerType
     
      }
      userErrors {
        field
        message
      }
    }
  }
`;
class UpdateTheText extends React.Component{
    static contextType = Context;
    render(){
        return(
            <Mutation mutation={UPDATE_TEXT}>
            {(handleSubmit, {error, data}) => {
              const [hasResults, setHasResults] = useState(false);
    
              const showError = error && (
                <Banner status="critical">{error.message}</Banner>
              );
    
              const showToast = hasResults && (
                <Toast
                  content="Successfully updated"
                  onDismiss={() => setHasResults(false)}
                />
              );
    
              return (
                <Frame>
                  {showToast}
                  <Layout.Section>
                    {showError}
                  </Layout.Section>
    
                  <Layout.Section>
                    <Stack distribution={"center"}>
                      <Button
                        primary
                        textAlign={"center"}
                        onClick={() => {
                          let promise = new Promise((resolve) => resolve());
                            const newmetafields = {
                                  key: "ExtraShopDesc",
                                  namespace: "ExtraShopDescription",
                                  ownerId: "gid://shopify/Shop/55595073672",
                                  type: "single_line_text_field",
                                  value: "This is an extra shop description twice"
                              }
    
                            promise = promise.then(() => handleSubmit({ variables: { metafields: newmetafields }}));
                          
    
                          if (promise) {
                            promise.then(() => this.props.onUpdate().then(() => setHasResults(true)));
                        }}
                      }
                      >
                        Update Text
                      </Button>
                    </Stack>
                  </Layout.Section>
                </Frame>
              );
            }}
          </Mutation>
        );
    }

}

export default UpdateTheText;

I believe i'm passing the variables into the gql but it doesn't seem to be picking them up?

Sigh,

This all along was an API version issue. Shopify CLI still spins up Oct 2020 API. Metafieldset was only added in the 2021 API

https://shopify.dev/api/admin-graphql/2021-10/mutations/metafieldsset

The error messages threw me off

So to update just update the API version in server.js

API_VERSION: "2021-10",
