URL: https://github.com/apache/airflow/issues/18110
### Apache Airflow version
2.0.0
### Operating System
Ubuntu 18.04.5 LTS
### Versions of Apache Airflow Providers
_No response_
### Deployment
Virtualenv installation
### Deployment details
_No response_
### What happened
CORS origin could not be enabled with airflow.cfg. We tried to trigger DAGs
from Angular UI
Angular version: 12+
Node.js version: 16+
Access to XMLHttpRequest at 'http://airflow.com/api/v1/dags/Samples/dagRuns'
from origin 'http://angularui.com:4200' has been blocked by CORS policy:
Response to preflight request doesn't pass access control check: No
'Access-Control-Allow-Origin' header is present on the requested resource.
example:
[API]
access_control_allow_headers = *
access_control_allow_methods = *
access_control_allow_origin = *
We tried following the docs, we restarted the server always. None of them
work.
### What you expected to happen
We expected to call an Airflow API and trigger DAGs from angular UI. But
CORS issue blocked call to the Airflow API.
### How to reproduce
1. Create a new angular project.
2. Create a button to make an Airflow API call using HttpClient.
3. Run it in production mode.
4. Click the button to trigger the API call.
5. Check chrome console.
### Anything else
