   same situation with the `operator` column in `task_instance` table
   i had to do 
   ```SQL
   UPDATE task_instance SET operator = 'NoOperator' WHERE operator IS NULL;
   ```
   should i open a new issue?
   
   ```python
   >>> import json
   >>> import requests
   >>> from requests.auth import HTTPBasicAuth
   >>> payload = {"dag_ids": ["{my_dag_id}"]}
   >>> r = requests.post("https://localhost:8080/api/v1/dags/~/dagRuns/~/taskInstances/list", auth=HTTPBasicAuth('username', 'password'), data=json.dumps(payload), headers={'Content-Type': 'application/json'})
   >>> r.status_code
   500
   >>> print(r.text)
   {
     "detail": "None is not of type 'string'\n\nFailed validating 'type' in schema['allOf'][0]['properties'][
   'task_instances']['items']['properties']['operator']:\n    {'type': 'string'}\n\nOn instance['task_instanc
   es'][5]['operator']:\n    None",
     "status": 500,
     "title": "Response body does not conform to specification",
     "type": "https://airflow.apache.org/docs/2.0.1/stable-rest-api-ref.html#section/Errors/Unknown"
   }
   None is not of type 'string'
   
   Failed validating 'type' in schema['allOf'][0]['properties']['task_instances']['items']['properties']['ope
   rator']:
       {'type': 'string'}
   
   On instance['task_instances'][5]['operator']:
       None
   ```
