Hi,
In the configuration, under the cron tab, you can configure the "Minimum delay between two cron tasks". So if you want the mass action to be triggered every minute by the cron task, you also need to set that setting to 1 minute.
Also, in that case, you can't use the cron task system we provide with the "Create/Edit your Cron task" button as we only offer a minimum of 15 minutes between each trigger of your cron task. Instead you need to configure the cron task on your own server:
