Restrictions on adding sub-automation in Automation(Lead Type Trigger)

Product behaviour: Sub-Automations created for an Activity type Trigger cannot be used in other automations with Lead type Triggers.

Root cause: Sub-automation cards for Lead Type Triggers have a validation that only allows Sub-automations created with the same trigger type.

Solution: The user can either create a new sub-automation using the Lead Type trigger or utilize an existing one created with the same trigger.

This validation only applies to Lead type Trigger automations. If the trigger is different (e.g., New Activity), you can add any existing sub-automation.
