### Apache Airflow version 2.3.3 (latest released) ### What happened In 2.3.3 If I use https://airflow.apache.org/docs/apache-airflow/stable/plugins.html#plugins-as-python-packages feature, then I see these Error: short: `ValueError: The name 'airs' is already registered for this blueprint. Use 'name=' to provide a unique name.` long: > i'm trying to reproduce it... If I don't use it(workarounding by AIRFLOW__CORE__PLUGINS_FOLDER), errors doesn't occur. It didn't happend in 2.3.2 and earlier ### What you think should happen instead Looks like plugins are import multiple times if it is plugins-as-python-packages. Perhaps flask's major version change is the main cause. Presumably, in flask 1.0, duplicate registration of blueprint was quietly filtered out, but in 2.0 it seems to have been changed to generate an error. (I am trying to find out if this hypothesis is correct) Anyway, use the latest version of FAB is important. we will have to adapt to this change, so plugins will have to be imported once regardless how it defined. ### How to reproduce > It was reproduced in the environment used at work, but it is difficult to disclose or explain it. > I'm working to reproduce it with the breeze command, and I open the issue first with the belief that it's not just me. ### Operating System CentOS Linux release 7.9.2009 (Core) ### Versions of Apache Airflow Providers ```sh $ SHIV_INTERPRETER=1 airsflow -m pip freeze | grep apache- apache-airflow==2.3.3 apache-airflow-providers-apache-hive==3.1.0 apache-airflow-providers-apache-spark==2.1.0 apache-airflow-providers-celery==3.0.0 apache-airflow-providers-common-sql==1.0.0 apache-airflow-providers-ftp==3.1.0 apache-airflow-providers-http==3.0.0 apache-airflow-providers-imap==3.0.0 apache-airflow-providers-postgres==5.1.0 apache-airflow-providers-redis==3.0.0 apache-airflow-providers-sqlite==3.1.0 ``` but I think these are irrelevant. ### Deployment Other 3rd-party Helm chart ### Deployment details docker image based on centos7, python 3.9.10 interpreter, self-written helm2 chart .... ... but I think these are irrelevant. ### Anything else _No response_ ### Are you willing to submit PR? - [X] Yes I am willing to submit a PR! ### Code of Conduct - [X] I agree to follow this project's [Code of Conduct](https://github.com/apache/airflow/blob/main/CODE_OF_CONDUCT.md) -- This is an automated message from the Apache Git Service.
