弹性搜索类型错误：fxn 不是函数

Question

我的项目的几个文件中有这段代码，我知道重复代码是不好的做法。所以我决定在不同的文件中编写一个函数来返回所需的结果，但它不起作用。这似乎是弹性搜索代码的特殊之处。这是我最初在 course.js 中工作正常的内容：

...

const { body: bulkResponse } = await client.bulk({ refresh: true, body });
    if (bulkResponse.errors) {
      const erroredDocuments = [];

      bulkResponse.items.forEach((action, i) => {
        const operation = Object.keys(action)[0];
        if (action[operation].error) {
          erroredDocuments.push({
            
            status: action[operation].status,
            error: action[operation].error,
            operation: body[i * 2],
            document: body[i * 2 + 1]
          });
        }
      });
      console.log(erroredDocuments);

...

然后我将 course.js 中的代码段替换为：

const {checkIfIndexExists, bulkIndexing } = require('../../utils/util')
...

bulkIndexing(body);

...


//in util.js i have this

/**
 * @description this function performs bulk index of model once the input array is prepared for indexing
 * @param {Array} indexBulkArray Array of index and the respective object to be indexed
 * @returns null
 */
const bulkIndexing = async (indexBulkArray)=>{
  try {
          const { body: bulkResponse } = await client.bulk({ refresh: true, body: indexBulkArray });
    if (bulkResponse.errors) {
      const erroredDocuments = [];
  
      bulkResponse.items.forEach((action, i) => {
        const operation = Object.keys(action)[0];
        if (action[operation].error) {
          erroredDocuments.push({
            
            status: action[operation].status,
            error: action[operation].error,
            operation: body[i * 2],
            document: body[i * 2 + 1]
          });
        }
      });
      console.log(erroredDocuments);
    }
  
          
      } catch (error) {
          console.log(error)
      }
    }

module.exports = {
  ...
  bulkIndexing,
  ...
};

我收到错误

TypeError: bulkIndexing is not a function
