In ZATCA, we have moved to production, and all the setups are completed, but invoices are not being sent automatically to the ZATCA portal. We have more than 25 shops, and invoices are created every minute but are not being processed to the ZATCA portal. We found a scheduled action named 'EDI: Perform web services operations.' Is this related to ZATCA, or do we need to create an automatic one? Please suggest a solution. We need a quick and urgent reply from your side. Additionally, when I clicked "Run Manually," I encountered an error message.
