我通过Google Calendar API不断收到“超出费用限制”的信息-不知道如何减少请求量了

如何解决我通过Google Calendar API不断收到“超出费用限制”的信息-不知道如何减少请求量了

每次运行脚本时，都会出现“超出速率限制”错误：

<HttpError 403 when requesting https://www.googleapis.com/calendar/v3/calendars/calednar-url/events/12345abcd? returned "Rate Limit Exceeded">

我已更改它，因此我在请求之间进行批处理并延迟1秒，以减少请求的数量，但仍然没有效果。

您能指导我解决该问题的方法吗？

该脚本的目的是将一群人的假期从主假期日历复制到仅开发者日历。

脚本每次运行时，都会从主日历获得上一年的每个假期，从开发日历中删除每个事件，然后仅将开发假期添加回开发日历。可能可以对其进行优化，但不确定哪种方法最好。
