Create invoice in Zoho Books gives "Invoice Number can't be empty" error

Create invoice in Zoho Books gives "Invoice Number can't be empty" error

Hi,

I get the following error when trying to create an invoice in Zoho Books through Zoho Flow: "Vous ne pouvez pas continuer si le champ numérique Invoice est vide. Entrez un nombre Invoice valide.",(screenshot 80), which would translate as: "Can'T create invoice if the invoice number is empty.

In Zoho Flow, it says that "Invoice Number is mandatory when Ignore Auto Number Generation is True".  My Ignore Auto Number Generation, however, is set to False. (Screenshot 81).

Thank you for you help!
