ERPNext Version 7 Email Scheduler Error - Celery or Redis Queue

Frappe Framework
1

Hi,

I have upgraded our system to Version 7.
Now I can able to send some of the email like password change and user creation.
But Email function for any document is not working.
As per my knowledge Celery is replaced with Redis Queue.
But still error log showing scheduler error related to Celery.
I got below error on the console.

Some of the email even not showing into Email Queue also.
I can able to send Queued email from Email Queue manually.

@sweetdharmik

Please check the Procfile in your bench, which must still have entries for the celery workers.

You can try running bench setup procfile, which will generate a new set of instructions for the bench to pickup RQ instead of Celery.

@shreyasp

I executed setup procfile. But procfile configuration does not change.
Here is my procfile content.

redis_cache: redis-server config/redis_cache.conf
redis_socketio: redis-server config/redis_socketio.conf
redis_queue: redis-server config/redis_queue.conf
web: bench serve --port 8000
socketio: /usr/bin/node apps/frappe/socketio.js
watch: bench watch
workerbeat: sh -c ‘cd sites && exec …/env/bin/python -m frappe.celery_app beat -s scheduler.schedule’
worker: sh -c ‘cd sites && exec …/env/bin/python -m frappe.celery_app worker -n jobs@%h -Ofair --soft-time-limit 360 --time-limit 390’
longjob_worker: sh -c ‘cd sites && exec …/env/bin/python -m frappe.celery_app worker -n longjobs@%h -Ofair --soft-time-limit 1500 --time-limit 1530’
async_worker: sh -c ‘cd sites && exec …/env/bin/python -m frappe.celery_app worker -n async@%h -Ofair --soft-time-limit 1500 --time-limit 1530’

Is it correct or Celery configuration should not be there in the file?
