We tried to use the StackDriver Error Reporting notification features, but it seems that for any Project, when we turn on the notification, it always sent to the email associated with the developer account that we logged in. How can we change it to a different email account. (we use PageDuty, and we want this notification to send to a pagerduty sink email account)
Today, email notifications on new errors for a given project are enabled per user and can only be delivered to the email associated with his user's account.
As a workaround, and if possible, you could setup an email filter that would forward these emails.
I am the Stackdriver Error Reporting product manager. It is not the first time we hear this feedback and we are working on improving the situation.
