Sitemap Scheduler Not Generating Sitemaps in AEM

[nerodhana]

I'm using AEM with the SitemapScheduler configuration to generate sitemaps on a scheduled basis. I've set up the scheduler with the following configuration:

{
  "scheduler.name": "Practice Daily Sitemap Scheduler",
  "scheduler.expression": "* * * * *",
  "searchPath": "/content/practice/us"
}

However, sitemaps are not being generated in /var/sitemaps, and I can't access them via the expected URLs. I've enabled on-demand sitemap generation, which is working fine. I've also ensured that the configuration file is placed under config.publish. Can someone help me identify why the scheduler isn't working as expected?

my crx de of author is : 

my crx de of publish is : 

when i turn on on demand sitemap generation it is getting generated like this : 

which is alright

the only problem is with the sitemap scheduler

please help me i have waited for one hour and still cannot see the sitemap 

Note : I am using aem as a cloud service sdk

@nerodhana :Are you trying to generate this every minute, seems un-usual (based on your cron - * * * * *).
Please check if there are errors in logs regarding this.
