**Apache Airflow version**: 2.0.1
**Kubernetes version (if you are using kubernetes)** (use `kubectl version`):
**Environment**: Linux
- **Cloud provider or hardware configuration**:
- **OS** (e.g. from /etc/os-release):
- **Kernel** (e.g. `uname -a`):
- **Install tools**:
- **Others**:
**What happened**:
Following the example here (https://github.com/apache/airflow/blob/master/airflow/example_dags/example_dag_decorator.py) I tried to add cc param for the email operator like below
```
@dag(default_args=DEFAULT_ARGS, schedule_interval=None, start_date=days_ago(2), tags=['example'])
def example_dag_decorator(email: str = 'example@example.com', email_cc: str = 'example2@example.com'):
"""
DAG to send server IP to email.
:param email: Email to send IP to. Defaults to example@example.com.
:type email: str
"""
get_ip = GetRequestOperator(task_id='get_ip', url="http://httpbin.org/get")
@task(multiple_outputs=True)
def prepare_email(raw_json: Dict[str, Any]) -> Dict[str, str]:
external_ip = raw_json['origin']
return {
'subject': f'Server connected from {external_ip}',
'body': f'Seems like today your server executing Airflow is connected from IP {external_ip}<br>',
}
email_info = prepare_email(get_ip.output)
EmailOperator(
task_id='send_email', to=email, cc=email_cc, subject=email_info['subject'], html_content=email_info['body']
)
dag = example_dag_decorator()
# [END dag_decorator_usage]
```
I get the following error:
cc = get_email_address_list(cc)
File "/opt/app-root/lib64/python3.8/site-packages/airflow/utils/email.py", line 213, in get_email_address_list
raise TypeError(f"Unexpected argument type: Received '{received_type}'.")
TypeError: Unexpected argument type: Received 'DagParam'.
<!-- (please include exact error messages if you can) -->
**What you expected to happen**:
CC parameter to work like the To parameter
<!-- What do you think went wrong? -->
**How to reproduce it**:
<!---
As minimally and precisely as possible. Keep in mind we do not have access to your cluster or dags.
If you are using kubernetes, please attempt to recreate the issue using minikube or kind.
## Install minikube/kind

- Kind https://kind.sigs.k8s.io/docs/user/quick-start/
If this is a UI bug, please provide a screenshot of the bug or a link to a youtube video of the bug in action
You can include images using the .md style of
To record a screencast, mac users can use QuickTime and then create an unlisted youtube video with the resulting .mov file.

**Anything else we need to know**:
I dont know if this is a bug or not if its not a bug can we mark this a feature request?

I think you are passing string to "cc=email_cc" instead of list of string that is why you are getting
TypeError(f"Unexpected argument type: Received '{received_type}'.")
Kindly check the official document describing arguments type of EmailOperator in below link :
https://airflow.apache.org/docs/apache-airflow/1.10.9/_modules/airflow/operators/email_operator.html
