[GitHub] [airflow] ephraimbuddy opened a new issue #12306: Getting list of taskInstances without start_date, end_date and state fails in REST API
ephraimbuddy opened a new issue #12306:
URL: https://github.com/apache/airflow/issues/12306
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:
```
{

}
],

}
```
**How to reproduce it**:
Call the endpoint `http://localhost:28080/api/v1//dags/~/dagRuns/~/taskInstances/list` with dags whose tasks instances have not started.
