Hi,
I have a report that is executed by a Scheduled Action every 3rd day of every month.
The problem that I have in Odoo12 is that the report is generated with no logos when the process is triggerd by the scheduller. This is the error that I found in the log:
2021-09-15 22:50:08,738 277558 WARNING Ecobano-pruebas \odoo.addons.base.models.ir_actions_report: wkhtmltopdf: b'Exit with code 1 due to network error: ContentNotFoundError\n'
The error is occuring regarless the server has NGINX install or not.
When I click on Run Manually (Scheduled Action most reports are generated with the logos but there are few that come out with no logos.
Did you check the wkhtmltopdf version and its compatibility with Odoo v12?
