Update to Lambda events logged in AWS CloudTrail

[sshvetsov]

Email from AWS

"""
Hello,

You are receiving this notification because we identified you have one or more Amazon CloudWatch rule(s) that monitor AWS Lambda API events logged through AWS CloudTrail. [1]

Previously, AWS Lambda API names were logged with a date suffix in the EventName for your CloudTrail logs. The event names changed as service APIs were enhanced with new features and capabilities. In order to simplify automation of log processing, we are now removing the date suffixes from the EventName. With this change, Lambda will only log documented API names in the EventName field as part of the CloudTrail event. The list of updated and old API events are listed in this message.

This change will roll out to your account on October 20, 2021. Before this date, please evaluate and update any automation workflows that process Lambda API events from CloudTrail logs to use the Event Name without date suffix.

Failing to update the event names in your automation may prevent you from performing the desired actions after calling Lambda APIs. If your automation relies on accessing the Lambda API version, you can use the apiVersion field in CloudTrail.

List of API event names that will be logged going forward:
