Unable to run scheduled tasks mentioned in hooks?

Frappe Framework Customization

Just trying to answer this query since alot of us face this issue and kind of are out of wits to know the real cause.
First of all thanks to @saurabh6790 for resolving this issue reference: WN-SUP29014.

This is how I have resolved this issue:

Step1:

  1. First Check if your code is working by `bench --site [site_name] execute [path_to_file]
  2. If your scheduled task code is fine then check if scheduler is working bench --site [site-name] trigger-scheduler-event all/hourly/daily/monthly
  3. Most probably this would not work since schedulers are not working
  4. Now try bench --site all clear-cache (and most probably this won’t work too)
  5. Now get into site console where the problem is bench --site [site-name] console
  6. Enter this command frappe.cache().get_value('scheduler_events'), this would show the events in your cache for scheduler and in my case the custom_app tasks were missing as below:
In [2]: frappe.cache().get_value('scheduler_events')
Out[2]: 
{u'all': [u'frappe.email.queue.flush',
  u'frappe.email.doctype.email_account.email_account.pull',
  u'frappe.email.doctype.email_account.email_account.notify_unreplied',
  u'frappe.oauth.delete_oauth2_data',
  u'frappe.integrations.doctype.razorpay_settings.razorpay_settings.capture_payment',
  u'frappe.twofactor.delete_all_barcodes_for_users'],
 u'daily': [u'frappe.email.queue.clear_outbox',
  u'frappe.desk.notifications.clear_notifications',
  u'frappe.core.doctype.error_log.error_log.set_old_logs_as_seen',
  u'frappe.desk.doctype.event.event.send_event_digest',
  u'frappe.sessions.clear_expired_sessions',
  u'frappe.email.doctype.email_alert.email_alert.trigger_daily_alerts',
  u'frappe.async.remove_old_task_logs',
  u'frappe.utils.scheduler.disable_scheduler_on_expiry',
  u'frappe.utils.scheduler.restrict_scheduler_events_if_dormant',
  u'frappe.email.doctype.auto_email_report.auto_email_report.send_daily',
  u'frappe.core.doctype.feedback_request.feedback_request.delete_feedback_request',
  u'frappe.core.doctype.authentication_log.authentication_log.clear_authentication_logs'],
 u'daily_long': [u'frappe.integrations.doctype.dropbox_settings.dropbox_settings.take_backups_daily',
  u'frappe.integrations.doctype.s3_backup_settings.s3_backup_settings.take_backups_daily'],
 u'hourly': [u'frappe.model.utils.link_count.update_link_count',
  u'frappe.model.utils.user_settings.sync_user_settings',
  u'frappe.utils.error.collect_error_snapshots',
  u'frappe.desk.page.backups.backups.delete_downloadable_backups',
  u'frappe.limits.update_space_usage'],
 u'monthly': [u'frappe.email.doctype.auto_email_report.auto_email_report.send_monthly'],
 u'monthly_long': [u'frappe.integrations.doctype.s3_backup_settings.s3_backup_settings.take_backups_monthly'],
 u'weekly_long': [u'frappe.integrations.doctype.dropbox_settings.dropbox_settings.take_backups_weekly',
  u'frappe.integrations.doctype.s3_backup_settings.s3_backup_settings.take_backups_weekly']}
  1. Now since the tasks were missing do sudo supervisorctl restart all now I got an issue here as some processes exited with error as below:
[frappe@www frappe-bench]$ sudo supervisorctl restart all
frappe-bench-workers:frappe-bench-frappe-schedule: stopped
frappe-bench-workers:frappe-bench-frappe-default-worker-0: stopped
frappe-bench-workers:frappe-bench-frappe-long-worker-0: stopped
frappe-bench-workers:frappe-bench-frappe-short-worker-0: stopped
frappe-bench-web:frappe-bench-frappe-web: stopped
frappe-bench-web:frappe-bench-node-socketio: stopped
frappe-bench-redis:frappe-bench-redis-queue: stopped
frappe-bench-redis:frappe-bench-redis-cache: stopped
frappe-bench-redis:frappe-bench-redis-socketio: stopped
frappe-bench-workers:frappe-bench-frappe-schedule: started
frappe-bench-workers:frappe-bench-frappe-default-worker-0: ERROR (abnormal termination)
frappe-bench-workers:frappe-bench-frappe-long-worker-0: started
frappe-bench-workers:frappe-bench-frappe-short-worker-0: started
frappe-bench-web:frappe-bench-frappe-web: started
frappe-bench-redis:frappe-bench-redis-cache: started
frappe-bench-redis:frappe-bench-redis-socketio: started
frappe-bench-web:frappe-bench-node-socketio: started
frappe-bench-redis:frappe-bench-redis-queue: started
[frappe@www frappe-bench]$
  1. Now do run this command to restart the failed process sudo supervisorctl restart frappe-bench-workers:frappe-bench-frappe-default-worker-0 see how we referenced the process name.
  2. Now again in site console after restarting the processes check with frappe.cache().get_value('scheduler_events')

Now if all the frappe-bench workers were started properly then you should be able to see your custom_app processes in the console output.
