getting many warnings for particular dags in airflow

I just recently installed airflow and whenever I execute a task, I get warning about different dags:

How do i get rid of these warnings ?

Unfortunately, this is known behavior for quite some time. There is a GitHub Discussion thread about this if you'd like to follow along.

Unless you don't mix TaskFlow tasks and classic operators, this warning will continue to persist. It's somewhat intrusive, but it doesn't impact functionality.
