Same problem is observed by me.
I manually checked the changes done by [minor] fallback to file upload #4151 and found all correction are available. I also checked the procfile and found all correct entries but in development mode it doesn’t work.
My procfile is as follows:
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 8001
socketio: /usr/bin/node apps/frappe/socketio.js
watch: bench watch
schedule: bench schedule
worker_short: bench worker --queue short
worker_long: bench worker --queue long
worker_default: bench worker --queue default
I am using Frappe version 9.0.0 and Erpnext version 9.0.0. and Ubuntu 16.04.3 LTS.
Please suggest if there is a solution as I need to load some test data using Import Export Tool.
