Problem after closing scheduler before pausing DAG

[Matheus-Homem]

Apache Airflow version

2.2.5 (latest released)

What happened

Coding its the same, I did't change and AirFlow stop working. I guess it is because I closed apache scheduler before pausing the DAG and then deleted the DAG.

`Something bad has happened.

Airflow is used by many users, and it is very likely that others had similar problems and you can easily find
a solution to your problem.

Consider following these steps:

• gather the relevant information (detailed logs with errors, reproduction steps, details of your deployment)

• find similar issues using:

  • GitHub Discussions
  • GitHub Issues
  • Stack Overflow
  • the usual search engine you use on a daily basis

• if you run Airflow on a Managed Service, consider opening an issue using the service support channels

• if you tried and have difficulty with diagnosing and fixing the problem yourself, consider creating a bug report.
  Make sure however, to include all relevant details and results of your investigation so far.

Don't use sqlite3 for anything resembling production. It WILL break it is not supposed to use to anything that quick start and playing in very early developlent. You've been warned.

https://airflow.apache.org/docs/apache-airflow/stable/howto/set-up-database.html?highlight=sqlite

By default, Airflow uses SQLite, which is intended for development purposes only.
