@vanessamarie1 On the screenshot that says "received invalid inputs", can you please expand the fields that say "Button" and "Recipient" (fully expand, as many levels deep as you can) and provide more screenshots? Somewhere in there it received some bad input data. I'm guessing that some field changed recently that broke the automation.
Similarly on the historic runs that were successful, can you please fully expand those and send more screenshots. Something has changed from the before and after. And expanding these should give some better clues. Thanks!
