Received invalid inputs

Hello,
I would like to populate automatically my airtable calendar/grid. But I’m testing it’s failing because the inputs is invalid but I don’t know why. There are no explanations. Does anyone already faced this problem ?

Thanks by advance.

I’m working on an automation right now that experienced that same thing. I ended up deleting all the fields in the actions and replacing them, updating and testing one by one until I found the failure. It ended up being trying to add text to a number field.
