Getting a list of taskinstances where some taskinstances does not have start date, end date and state fails **Apache Airflow version**: 2.0 **What happened**: Calling the endpoint `http://localhost:28080/api/v1//dags/~/dagRuns/~/taskInstances/list` with dags whose tasks instances have not started fails. ``` { "detail": "None is not of type 'string'\n\nFailed validating 'type' in schema['allOf'][0]['properties']['task_instances']['items']['properties']['start_date']:\n {'format': 'datetime', 'type': 'string'}\n\nOn instance['task_instances'][9349]['start_date']:\n None", "status": 500, "title": "Response body does not conform to specification", "type": "https://airflow.readthedocs.io/en/latest/stable-rest-api-ref.html#section/Errors/Unknown"; } ``` **What you expected to happen**: I expected to see a list of task instances like this: ``` { "task_instances": [ { "dag_id": "latest_only", "duration": 0.481884, "end_date": "2020-11-11T22:03:03.822310+00:00", "execution_date": "2020-11-10T12:00:00+00:00", "executor_config": "{}", "hostname": "7b6c973dde4b", "max_tries": 0, "operator": "LatestOnlyOperator", "pid": 1943, "pool": "default_pool", "pool_slots": 1, "priority_weight": 2, "queue": "default", "queued_when": "2020-11-11T22:03:02.648502+00:00", "sla_miss": null, "start_date": "2020-11-11T22:03:03.340426+00:00", "state": "success", "task_id": "latest_only", "try_number": 1, "unixname": "root" }, { "dag_id": "example_branch_dop_operator_v3", "duration": null, "end_date": null, "execution_date": "2020-11-11T02:18:00+00:00", "executor_config": "{}", "hostname": "", "max_tries": 0, "operator": "BranchPythonOperator", "pid": null, "pool": "default_pool", "pool_slots": 1, "priority_weight": 3, "queue": "default", "queued_when": null, "sla_miss": null, "start_date": null, "state": null, "task_id": "condition", "try_number": 0, "unixname": "root" } ], "total_entries": 2 } ``` **How to reproduce it**: Call the endpoint `http://localhost:28080/api/v1//dags/~/dagRuns/~/taskInstances/list` with dags whose tasks instances have not started. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
