How to reproduce it:

I wanted to take an Action on a task instance of a DAG with schedule_interval=None. I am attaching a minimal DAG file used for reproducing this error.

DAG file

from airflow import DAG
from datetime import timedelta, datetime
from airflow.operators.bash_operator import BashOperator

dag = DAG(
    'simple_dag',
    default_args= {
        'owner': 'airflow',
        'depends_on_past': False,
        'retries' : 0,
        'start_date': datetime(1970, 1, 1),
        'retry_delay': timedelta(seconds=30),
    },
    description='',
    schedule_interval=None,
    catchup=False,
)

t1 = BashOperator(
    task_id='task1',
    bash_command='echo 1',
    dag=dag
)

Anything else we need to know:

Taking the same Action on the DagRun list (http://localhost:8080/dagrun/list) works.

Great project btw 🙌. Really enjoying using it.

Any ideas here @ashb @mik-laj @ryanahamilton ? I was able to reproduce this

I was able to reproduce as well. The UI refresh updates didn't touch anything related to this. I thought the recent FAB upgrade from 3.0 to 3.1 could be the culprit, but I just tested the commit prior to that upgrade and was able to reproduce with FAB 3.0 as well.

Seeing this too; at /taskinstance/list/?_flt_0_state=queued#, selected all tasks, tried to clear them.
