Ruby on rails 如何解决“错误”；Can'；t在只读日历上创建事件；从尼拉斯来的？

我正在Ruby on Rails应用程序中使用nylas。
我使用谷歌作为我在尼拉斯的供应商。我想在谷歌日历中添加一个活动。
在google中进行身份验证后，google将

刷新令牌

返回给我。我用它将这封邮件添加到nylas。最后，nylas向我发送了一个

访问\u令牌



以下几行是我使用的谷歌范围：

openid
email
profile
https://www.googleapis.com/auth/userinfo.email
https://www.google.com/m8/feeds/
https://www.googleapis.com/auth/userinfo.profile 
https://mail.google.com/  
https://www.googleapis.com/auth/calendar 
https://www.googleapis.com/auth/calendar.events

现在，我想用下面的代码片段向日历中添加一个事件

nylas = Nylas::API.new(app_id: "My_nylas_app_id",app_secret: "My_nylas_app_secret", access_token: "user_access_token")

calendar = nylas.calendars.first()

nylas.events.create(title: "A fun event!", location: "The Party Zone", calendar_id: calendar.id,when: { start_time: Time.now + 60, end_time: Time.now + 120 }).to_h

并且，上述代码段返回以下错误：
