zachliu opened a new issue #14635:
URL: https://github.com/apache/airflow/issues/14635
**Apache Airflow version**: 2.0.1
**Environment**: Docker on Linux Mint 20.1, image based on
apache/airflow:2.0.1-python3.8
**What happened**:
when i made this PATCH request to the API:
```python
>>> import json
>>> import requests
>>> from requests.auth import HTTPBasicAuth
>>> payload = {"dag_id": "example_bash_operator", "is_paused": False}
>>> r =
requests.patch('https://localhost:8080/api/v1/dags/example_bash_operator?update_mask=["is_paused";]',
auth=HTTPBasicAuth('username', 'password'), data=json.dumps(payload),
headers={'Content-Type': 'application/json'})
```
the following error occurred
```
HTTP response body: {
"detail": "Property is read-only - 'dag_id'",
"status": 400,
"title": "Bad Request",
"type":
"https://airflow.apache.org/docs/2.0.1/stable-rest-api-ref.html#section/Errors/BadRequest";
}
```
**What do you think went wrong?**:
The `requestBody` of the `patch` request is defined to use the `DAG` schema:
https://github.com/apache/airflow/blob/33910d6c699b5528db4be40d31199626dafed912/airflow/api_connexion/openapi/v1.yaml#L423-L428
But the `dag_id` property in the `DAG` schema has been defined as
`readOnly`:
https://github.com/apache/airflow/blob/33910d6c699b5528db4be40d31199626dafed912/airflow/api_connexion/openapi/v1.yaml#L1452-L1455
And according to https://github.com/zalando/connexion/issues/942, we'll get
a 400 error
**Anything else we need to know**:
This is not exactly an issue on Airflow's side. Unless someone thinks we
should remove `UpdateMask` from the specs.
