`source` is one of `AppflowBaseOperator`'s template fields, but it was validated against `SUPPORTED_SOURCES` inside `__init__`, which runs before Jinja rendering — so a templated `source` was rejected at Dag parse time with the raw expression in the error message. This moves the check to the top of `execute()`, where the rendered value is available, and removes the class from the exemption list. related: #70296 --- ##### Was generative AI tooling used to co-author this PR? - [X] Yes — Claude Code (Fable 5) Generated-by: Claude Code (Fable 5) following [the guidelines](https://github.com/apache/airflow/blob/main/contributing-docs/05_pull_requests.rst#gen-ai-assisted-contributions) -- This is an automated message from the Apache Git Service.
