Dear all,

There's the situation.
I deployed Zabbix 7.2.4 on our k8s cluster, and Zabbix server is using zabbix-server-mysql:7.2.4-ubuntu image.
There're several conf files under the directory /etc/zabbix in the Zabbix server pod.
The report conf is zabbix_server_reports.conf, and the content is like below.

### Option: StartReportWriters
#       Number of pre-forked report writer instances.
#
# Mandatory: no
# Range: 0-100
# Default:
# StartReportWriters=0
 
StartReportWriters=${ZBX_STARTREPORTWRITERS}
 
### Option: WebServiceURL
#       URL to Zabbix web service, used to perform web related tasks.
#       Example: [URL]http://localhost:10053/report[/URL]
#
# Mandatory: no
# Default:
# WebServiceURL=
 
WebServiceURL=${ZBX_WEBSERVICEURL}

I have built the zabbix server image with env set as blow.

StartReportWriters=10
WebServiceURL=http://<zabbix-web-nodeport-ip>:30053/report

Zabbix server pod's port mapping is set as below.

When I navigate to the web portal: Reports -> Scheduled reports select one and click the Test button, it gives me an error:
Report generating test failed.
The frontend URL has not been configured.

So, what steps should I do to normally generate the reports?
