加载项请求重复数据时e.importFromSeriesTimeJsonObject中的OWA崩溃

问题描述

新的Outlook日历条目。设置定期（例如每天几天）并启动Outlook加载项。

Outlook加载项代码：

const stLocal: Date = await GetoutlookTimeAsync(this.OutlookEvent.start);
const edLocal: Date = await GetoutlookTimeAsync(this.OutlookEvent.end);
const recurrence: Office.Recurrence = await GetoutlookStructureAsync("recurrence",this.OutlookEvent.recurrence);

.. snip ..

export const GetoutlookStructureAsync = (func: string,evt: any) => {
  return new Promise<any>((resolve,reject) => {
    const who: string = "GetoutlookStructure " + func;
    DebugLog(who,"Start");
    evt.getAsync((asyncResult: Office.AsyncResult<any>) => {
      if (asyncResult.status === Office.AsyncResultStatus.Succeeded) {
        DebugLog(who,JSON.stringify(asyncResult.value));
        resolve(asyncResult.value);
      } else {
        const errorText: string = asyncResult.error.message;
        DebugLog(who,errorText);
        reject(new Error(errorText));
      }
    });
  });
};

浏览器控制台显示：
