shan-zeeshan786 opened a new issue, #65391:
URL: https://github.com/apache/airflow/issues/65391
### Under which category would you file this issue?
Airflow Core
### Apache Airflow version
3.2.0
### What happened and how to reproduce it?
Recently, we changed the Fernet key in our environment. After this change,
we started observing 500 Internal Server Errors when accessing Variables via
the Stable REST API.
API Call:
GET /api/v1/variables/{key}
**Request:**
curl -X GET "http://<- airflow-webserver ->/api/v1/variables/<-
variable_name ->" \
-H "accept: application/json" \
-H "Authorization: Basic <base64-credentials>"
**Response:**
{
"detail": "None is not of type 'string'\n\nFailed validating 'type' in
schema['allOf'][1]['properties']['value']:\n{'type': 'string'}\n\nOn
instance['value']:\n None",
"status": 500,
"title": "Response body does not conform to specification",
"type":
"https://airflow.apache.org/docs/apache-airflow/3.2.0/stable-rest-api-ref.html#section/Errors/Unknown";
}
### What you think should happen instead?
The API should handle undecryptable Variable values gracefully instead of
returning a 500 error.
Possible expected behaviors:
- Return a 200 response with value as null or masked
- OR return a clear 4xx error indicating decryption failure
- OR include a meaningful error message (e.g., "Unable to decrypt variable
with current Fernet key")
At minimum, the response should not violate the OpenAPI schema and should
not result in a 500 Internal Server Error.
