missing one step to start asynchronous tasks consumption and that's causing all RAG knowledge in queuing status

Installed dify-on-eks according to steps mentioned in dify-cdk-cn successfully. however function failed when user uploads files to create knowledge (RAG), in queuing status for ever.
after checking dify document, below step is missing and that's for async queue consumption.
poetry run celery -A app.celery worker -P gevent -c 1 -Q dataset,generation,mail,ops_trace --loglevel INFO
e.g. https://docs.dify.ai/getting-started/install-self-hosted/local-source-code

similar like flask db upgrade, i've run that also in dify-api pod, now it's working. please check and make sure that's the case for version older than 0.8.2
