我使用Gmail API进行生产中的自动电子邮件处理已经有好几个月了.自2020年7月2日以来，突然看到尝试访问Gmail API的错误消息.

返回 呼叫者没有权限"

已检查Gmail仪表板，并且凭据处于活动状态，注意到已删除或修改.
Checked Gmail Dashboard and the credentials are active noting was removed or modified.
检查代码，可以确认3-4个月内没有任何更改.
Checked code and can confirm nothing changed for 3-4 months.
而且我们没有使用旧令牌.我们的代码将处理过期的凭证，并进行令牌刷新.
And we are not using old token. Our code takes care of expired credentials and does a token refresh.
还尝试删除token.pickle文件，当使用Gmail身份验证屏幕重新运行重新验证并重新创建token.pickle文件时，但错误消息无法解决.
Also tried removing the token.pickle file, when rerun re-authenticated using the Gmail Auth screen and token.pickle file is recreated however the error message cannot be resolved.
看来Google的情况有所改变.
It looks like something changed in Google's end.
有人可以确认吗?
