What happened: pickle _thread.RLock objects

What you expected to happen:

How to reproduce it:
1.
default_args = {
'owner': 'xxx',
'depends_on_past': False,
'start_date': datetime(2020, 4, 6),
'email': ['xxx@xxx.com'],
'email_on_failure': False,
'email_on_retry': False,
'retries': 0,
'retry_delay': timedelta(minutes=5),
'on_failure_callback': notifier.failure_callback
}
2. notifier = Notifier(subscribers=[Notifier.MSG], phone_receivers="111111111111",
email_receivers="xxxxx@xxxxx.com")

3. dag = DAG('xxxxxxx',
   default_args=default_args,
   schedule_interval='01 20 * * *')
4. UI throw exception， pickle _thread.RLock objects ，however in the logfile throwing TypeError: cannot serialize '_io.TextIOWrapper' object

Anything else we need to know:

This is not to do with default_args but to do with Logger object, what operator are you using ?
