Based on your screenshot, it looks like the expected value for that field was a number (likely the Customer ID) but you’ve added a name there instead. If you were doing something like creating (or finding) a customer, and then trying to use that customer for the payment, then you would use a custom value and map the ID that you get from the Create/Find Customer step.
Does that sound like your workflow, and if so does my explanation help at all?
