I have a lambda function setup and tested via manual triggers. I want this function to run once every day at mid-day.
To achieve this I created a new CloudWatch Events - Schedule trigger with a Schedule expression of cron(0 12 ? * * *).
With the function and trigger enabled, the function was not invoked. What should the correct Schedule expression be?
The cron expression was correct. Remember that your AWS region may not be in the same timezone and adjust your expectations accordingly.
