sum agregation is not working after migrate from zabbix 5.0 to zabbix 6.4

[marckam]

After migrate the zabbix server, this formula is not working anymore:

Key: grpsum["groupname","MKTK.Wan.in",last]

Formula: sum(last_foreach(/*/MKTK.Wan.in?[group="groupname"]))

I have this error

• Cannot evaluate expression: no input data for function at "sum(last_foreach(/*/MKTK.Wan.in?[group="groupname"]))"

Any help?

Thanks
