Should be a simple automation so I'm certain it's user error but I can't find my mistake.

I have a date value. When that date value is updated I want a single-select record to automatically update to "Date Changed"

Use case is to generate a weekly email via a separate automation that shows all rows that had a changed date in a given week.

My error is "Received invalid inputs."

Please let me know if you need more details/context and thank you in advance.
