Question: i am running the airflow pipeline but codes looks seems good but actually i'm getting the airflow.exceptions.AirflowException: Cycle detected in DAG. Faulty task: 
can u please help to resolve this issue

Answer: 
This can happen due to duplicate task\_id'a in multiple tasks.
Without the code, it's kind of hard to help you. However, this means that you have a loop in your DAG. Generally, thie error happens when one of your task has a downstream task whose own downstream chain includes it again (A calls B calls C calls D calls A again, for example). 
That's not permitted by Airflow (and DAGs in general).
