What's missing?

I've scoured the API documentation and web for a solution to this error but no matter what I do I am unable to clear the Creditmemo Document Validation Error(s):\nThe credit memo's total must be positive. error for Credit Memo creation via the order API. My payload (included below) is simple and follows the documentation examples but I cannot resolve the error. Why is the credit memo not creating?
