Excel中的异步自定义函数添加总是返回#BUSY！错误

如何解决Excel中的异步自定义函数添加总是返回#BUSY！错误

我一直在尝试使用异步自定义函数，并尝试了来自Office-add-in在线文档的样本，但是它们始终返回#BUSY !，没有异步函数可以正常工作，因此我假设清单文件已建立正确。

这是我的functions.js和functions.json文件中的示例代码。

function.js

async function getStarCount(userName,repoName) {
  try {
    //You can change this URL to any web request you want to work with.
    const url = "https://api.github.com/repos/" + userName + "/" + repoName;
    const response = await fetch(url);
    //Expect that status code is in 200-299 range
    if (!response.ok) {
      throw new Error(response.statusText)
    }
      const jsonResponse = await response.json();
      return jsonResponse.watchers_count;
  }
  catch (error) {
    return error;
  }
}

/**
 * @customfunction
 * @param address range's address
 **/
async function getRangeValue (address) {
  var context = new Excel.RequestContext();
  var range = context.workbook.worksheets.getActiveWorksheet().getRange(address);
  range.load();
  await context.sync();
  return range.values[0][0];
 }

CustomFunctions.associate("STARCOUNT",getStarCount);
CustomFunctions.associate("RANGEVALUE",getRangeValue);

functions.json
