Have recently update my Zabbix estate from 5.4 to 7.02.
5.4 Was running on Ubuntu as a standard app, with mysql, 7.0.2 is now running on Docker (24.0.9) using images :zabbix-server-mysql,zabbix-web-nginx-mysql,zabbix-web-service.
Following this update, which has otherwise been without issue on the server, whenever I edit a map, I get the following error:

The maps work fine, the Icons and pix all look fine... but always the same 7 line at the beginning.
This is also true if create a new map... with nothing on it!
As stated, there appears to be no operational issue as a result, but I wonder what I need to do to fix this.
