shan-zeeshan786 opened a new issue, #65377:
URL: https://github.com/apache/airflow/issues/65377
### Under which category would you file this issue?
Airflow Core
### Apache Airflow version
2.11.0
### What happened and how to reproduce it?
When calling the Airflow Stable REST API endpoint /api/v1/pools, the API
returns a 500 Internal Server Error if any pool has infinite slots configured
(represented internally as inf).
Steps to Reproduce:
1. Create or configure an Airflow pool with infinite slots / unlimited slots.
2. Call the Stable REST API endpoint:
Request:
curl -X GET "http://<airflow-webserver>/api/v1/pools?offset=0&limit=100" \
-H "accept: application/json" \
-H "Authorization: Basic <base64-auth>"
Response:
{
"detail": "inf is not of type 'integer'\n\nFailed validating 'type' in
schema['allof'][0]['properties']['pools']['items']['properties']['open_slots']:\n{'type':'integer',
\n 'readonly' :True, \n 'description':'The number of free slots at the
moment.')\n\nOn instance['pool'][0]['open_slot']:\n inf",
"status": 500,
"title": "Response body does not conform to specification",
"type":
"https://airflow.apache.org/docs/apache-airflow/2.11.0/stable-rest-api-ref.html#section/Errors/Unknown";
}
### What you think should happen instead?
The /api/v1/pools endpoint should return a valid successful response even
when a pool has infinite/unlimited slots configured.
Currently, the API breaks because the serialized response does not conform
to its own schema definition.
