Email By scheduler events

i have created server script for perticular Doctype to send email daily at morning 10:00 AM

I have created an schedular event hooks.py

scheduler_events = {
“cron”: {
“10 08 * * *”: [
“contract_management.contract_management.doctype.project_setup.project_setup.send_open_project_reminders”
]
}
}

My sheduler and bench worker also enabled

This timestamp and timestapm of my machine also same
that is UTC time

i am using ubuntu

i have tried both the following methods

frappe.enqueue and frappe.sendmail

my server script is also correct
i have triggred it using custom button that was created by client script

but i am unable to trigger my server script using scheduler_events

what may be problem behind this

is the job listed in /app/scheduled-job-log? else you may need to run migrate
