From the above message, I can understand that you are trying to create an e-invoice from an invoice whose document date is set in the future.
Please note that you cannot create an e-invoice with a future-dated invoice.
Please ensure that the invoice date is today’s date or a past date - future dates are not allowed as per e-invoice regulations.
Update the document date to a valid (non-future) date, try again, and let us know if you are facing any concerns.
