WooCommerce to Zoho Books says "Statement of Accounts does not exist."

WooCommerce to Zoho Books says "Statement of Accounts does not exist."

I have created a flow that is triggered by a completed WooCommerce order. It creates a closed/won deal, updates a date field in the customer account and is supposed to create an invoice in Zoho Books. The first two work, but the last part returns an error of  "Zoho Books says "Statement of Accounts does not exist."" What triggers this and what should I put in the Flow for it to function? I have attached the Books part from the Flow test & debug screen.
