Item Update interval at specific time

[ChrisJackson]

I'm trying to set an Item Update Interval to every day at 4 am.

I have looked and tried the information on
https://www.zabbix.com/documentation/4.2/manual/config/items/item/custom_intervals

If I set the update interval to "h4" hoping to collect data at 4 am every day I get a warning comes up saying
Field "Update interval" is not correct: a time unit is expected

What am I missing?

Use this scheduling interval

wd1-7h4

When I use wd1-7h4
I get "Field "Update interval" is not correct: a time unit is expected".

This is an active agent

Custom intervals NOT available for Zabbix agent active items.
