FastAPI DAGResponse does not strip whitespace in comma-separated owners #52215
Description
Apache Airflow version
3.0.2
If "Other Airflow 2 version" selected, which one?
No response
What happened?
When defining multiple DAG owners as a comma-separated string with spaces (e.g., "owner1, owner2, owner3"), the FastAPI response returns owner names with leading spaces, such as ["owner1", " owner2", " owner3"]. This causes inconsistent display in the UI and potentially breaks consumers expecting clean owner names.
What you think should happen instead?
The owners should be returned as a clean list of strings, with whitespace stripped:
["owner1", "owner2", "owner3"]
How to reproduce
default_args={
"owner": "owner1, owner2, owner3"
},
