So my invoicing report doesn't have any templates or design and it appears only as black and white text. For additional context , we use odoo community version 18 and it is self-hosted on our VPS using docker containers and it has a domain that is reverse proxied using Nginx . Now i've seen somewhere that i should add a report.url on the system parameters but my question is what should be the "value" of my report.url for this to work because I tried the one's I read but their deployment is more of a direct installation instead of docker and it doesn't work on mine, thank you very much in advance to anyone who could assist me
