Description
Apache Airflow version
2.5.1
What happened
when i run the code i cant see the dags graph
What you think should happen instead
the dag must appears in the graph view
How to reproduce
run this code
from airflow.decorators import dag,task
from datetime import datetime
@task
def make_list():
return [1, 2, 3, 4]
@task
def consumer(arg):
print(arg)
@task
def add_one(arg):
if(arg == 3):
raise ValueError("the value is 3 ")
return arg+1
@dag(dag_id="dynamic-task-map",
start_date=datetime(2022, 4, 2),
catchup=False)
def create_dag():
add_one_to_list = add_one.expand(arg=make_list())
consumer.expand(arg=add_one_to_list)
dag_instance = create_dag()

# Basic Airflow cluster configuration for CeleryExecutor with Redis and PostgreSQL.
#
# WARNING: This configuration is for local development. Do not use it in a production deployment.
#
# This configuration supports basic configuration using environment variables or an .env file
# The following variables are supported:
#
# AIRFLOW_IMAGE_NAME - Docker image name used to run Airflow.
# Default: apache/airflow:2.5.1
# AIRFLOW_UID - User ID in Airflow containers
# Default: 50000
# AIRFLOW_PROJ_DIR - Base path to which all the files will be volumed.
# Default: .
# Those configurations are useful mostly in case of standalone testing/running Airflow in test/try-out mode
#
# _AIRFLOW_WWW_USER_USERNAME - Username for the administrator account (if requested).
# Default: airflow
# _AIRFLOW_WWW_USER_PASSWORD - Password for the administrator account (if requested).
