Issue with Cron Job Timing in OpenWhisk Alarms

Hello,

We are encountering a challenge with the setup of cron jobs using the OpenWhisk Alarms feature, which is part of the Adobe App Builder Runtime.

Initially, we configured a trigger to invoke an action at 14:00 UTC as follows:

triggers:
  scheduleNightSync:
    feed: /whisk.system/alarms/alarm
    inputs:
      cron: 0 14 * * *
      timezone: UTC

However, due to a requirement change, we need to adjust this trigger time to 13:00 UTC.

 

To update the cron timing, we followed these steps:

1. Removed the existing trigger from the Runtime: `[aio rt:trigger:delete scheduleNightSync]`
2. Changed the cron schedule in the `app.config.yaml` file: `[cron: 0 13 * * *]`
3. Fully deployed the application: `[aio app deploy | aio app deploy --force-deploy]`
4. Retrieved the updated configuration of the trigger: `[aio rt:trigger:get scheduleNightSync]`. It shows the updated cron schedule: `{ "key": "cron", "value": "0 13 * * *" }`

Despite completing these steps, the trigger still invokes the action at 14:00 UTC instead of the intended 13:00 UTC.

 

I would appreciate any suggestions on how to resolve this issue. Thank you in advance for your assistance!
