How to manually trigger EventBridge Schedule?

This is really great question, as there is no way of doing that until you change the schedule for next minute and wait a minute to invoke it.

I do this quite often and here is how I do it via CLI, which is very handy way of doing this:

Let's say, right now time is 21:26EST and I want my lambda function to be invoked now, so I'll update my schedule as below

 aws scheduler update-schedule --name <Schedule_name> --schedule-expression "cron(27 21 * * ? *)" --flexible-time-window '{ "Mode": "OFF" }' --target '{ "Arn": "<Lambda_Function_Arn>", "RoleArn": "<Role_Arn_Used_In_Scheduler>" }' --profile <CLI_Profile_Name>

As my lambda function gets invoked, I'll revert the changes as below considering 12:00am is your actual schedule:

 aws scheduler update-schedule --name <Schedule_name> --schedule-expression "cron(00 00 * * ? *)" --flexible-time-window '{ "Mode": "OFF" }' --target '{ "Arn": "<Lambda_Function_Arn>", "RoleArn": "<Role_Arn_Used_In_Scheduler>" }' --profile <CLI_Profile_Name>

This may not be the exact answer, but this is very handy comparing to updating the same on console.

Hope you find this helpful.

Hello.

As far as I know, there is no way to do it manually.
Therefore, if you want to check the operation, I think it is best to try shortening the cron interval for now.
