zabbix 5.4.0
I use standard templates in messages, but when a message arrives in my mail or webhook, I don't receive all the data. Example, the template is like this
 

Problem started at {EVENT.TIME} on {EVENT.DATE}
Host: {HOST.NAME}
Host IP: {HOST.IP}
Severity: {EVENT.SEVERITY}
Operational data: {EVENT.OPDATA}
Original problem ID: {EVENT.ID}

 
I got it

Operational data: {EVENT.OPDATA}
