[GitHub] [airflow] aspain opened a new issue, #23017: Blank red `error:` bar intermittently showing in DAG, localhost UI briefly became unavailable
aspain opened a new issue, #23017:
URL: https://github.com/apache/airflow/issues/23017
### Apache Airflow version
2.2.5 (latest released)
### What happened
I was running a localhost instance of Astro Runtime 4.24, based on Airflow 2.2.5 and was testing two DAGs.
During a DAG run, a blank red `error:` bar appeared briefly (it went away and came back several times). Screenshot of the error bar below along with the output in the network console at the time.
At one point, when I refreshed the UI, it became entirely unavailable for about 1 minute:
Eventually the page became available again, and the DAGs ran successfully.
### What you think should happen instead
There is no actual error displayed, just text `error:` with an empty red bar. If something is actually wrong, the error should appear in the red bar. If nothing is actually wrong, there should be no error bar/message.
### How to reproduce
1. spun up a localhost instance using astrocloud cli
2. Had two DAGs running - one DAG where I was using a BashOperator to use the `airflow backfill dags` command to backfill another DAG as a test.
If relevant, the backfill trigger dag code is:
```
from airflow import DAG
from airflow.operators.bash import BashOperator
from datetime import datetime
with DAG(dag_id='backfill_trigger_dag',
schedule_interval=None,
start_date=datetime(2022, 1, 1),
catchup=False) as dag:
trigger_backfill = BashOperator(
task_id='trigger_backfill',
bash_command='airflow dags backfill -s 20220401 -e 20220410 example_dag_basic',
)
trigger_backfill
```
and the DAG it was triggering is:
```
from airflow import DAG
from airflow.operators.dummy import DummyOperator
from datetime import datetime, timedelta
from airflow.operators.python import PythonOperator
from airflow.operators.bash import BashOperator
default_args = {
'retries': 0,
'retry_delay': timedelta(minutes=5)
}
def pass_xcom(**kwargs):
my_xcom = "This string will be passed as an xcom by returning it"
return my_xcom
def pull_xcom(ti):
my_xcom = ti.xcom_pull(key='return_value', task_ids=['pass_xcom'])
print(my_xcom)
with DAG(dag_id='example_dag_basic',
default_args=default_args,
schedule_interval="@daily",
start_date=datetime(2022, 1, 1),
catchup=False) as dag:
start = DummyOperator(
task_id='start')
pass_xcom_task = PythonOperator(
task_id='pass_xcom_task',
python_callable=pass_xcom
)
pull_xcom_task = PythonOperator(
task_id='pull_xcom_task',
python_callable=pull_xcom
)
bash_task = BashOperator(
task_id='bash_task',
bash_command='echo Hello, world!'
)
finish = DummyOperator(
task_id='finish')
start >> pass_xcom_task >> pull_xcom_task >> bash_task >> finish
```

I'll work on replicating this locally and figure out which steps to address:
- Prevent the UI from crashing on an error
- Prevent the error in the first place
- At least include a message in the error
