### 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 ``` ### Operating System macOS 11.5.2 ### Versions of Apache Airflow Providers apache-airflow-providers-amazon==3.2.0 apache-airflow-providers-celery==2.1.3 apache-airflow-providers-cncf-kubernetes==3.0.0 apache-airflow-providers-databricks==2.5.0 apache-airflow-providers-elasticsearch==3.0.2 apache-airflow-providers-ftp==2.1.2 apache-airflow-providers-google==6.7.0 apache-airflow-providers-http==2.1.2 apache-airflow-providers-imap==2.2.3 apache-airflow-providers-microsoft-azure==3.7.2 apache-airflow-providers-postgres==4.1.0 apache-airflow-providers-redis==2.0.4 apache-airflow-providers-slack==4.2.3 apache-airflow-providers-snowflake==2.6.0 apache-airflow-providers-sqlite==2.1.3 ### Deployment Astronomer ### Deployment details AstroCloud CLI Version: 1.3.3 Docker Desktop 4.3.0 ### Anything else Today was the first time I have noticed this issue ### Are you willing to submit PR? - [ ] Yes I am willing to submit a PR! ### Code of Conduct - [X] I agree to follow this project's [Code of Conduct](https://github.com/apache/airflow/blob/main/CODE_OF_CONDUCT.md) -- This is an automated message from the Apache Git Service.
