Check the automation's name, trigger, and actions.
The "Create automation" wizard's own validation caught a problem before saving - e.g. a keyword trigger with no keywords, or a follow-up trigger with no delay set.
Check the automation's name, trigger, and actions for anything missing.
Add the missing keywords or delay.
Try saving the automation again.
