【问题描述】：

我最近一直在玩 Shopify 应用程序开发，我正在努力使用 graphql 调用来修改一些文本。下图显示了在我测试它的 shopify GraphQL 应用程序中正确进行的调用。

但是，当我尝试从 react 组件进行同样的调用时，我收到以下错误

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

这是我尝试更新元字段的反应组件

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;

我相信我正在将变量传递给 gql，但它似乎没有接收到它们？

【解决方案1】：

叹息，

这一直是 API 版本问题。 Shopify CLI 仍在启动 Oct 2020 API。 Metafieldset 仅在 2021 API 中添加

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

错误消息让我失望

所以要更新只需更新 server.js 中的 API 版本

API_VERSION: "2021-10",
