My cron expression in DB_connect App does not work, even if the cron expression works in Alert.

Hello Splunker,

The following cron expression does not work in the input setting of Splunk DB connect App (v3.1.4) on Splunk server (v7.3.0).

0 * 1-25 * 0

And it is shown the message;
"invalid interval, must be an integer or cron expression."

I have already checked the expression in the site;
https://crontab.guru/

Also it is weird for the expression to work in alert setting.
I would like to run the input setting at minute 0 on every day-of-month from 1 through 25 and on Sunday.

I appreciate any advice and idea to let the schedule work in DB connect.

Regards,

0 * 1-25 * *

This cron expression works in the app!
But this is now what I want to do.
