422 root cause related with this https://github.com/fastapi/fastapi/issues/1431

first)
I added this logic to manually convert the request body to a LoginBody instance when it’s received as a dictionary (e.g., from application/x-www-form-urlencoded).

changed my mind)
I think that airflow needs to support both application/json and application/x-www-form-urlencoded content types.

This helps prevent FastAPI from raising a 422 Unprocessable Entity error due to automatic validation failure.

#53567 related. (first this pr merged -> 53597)

"Using the RequestBody option in Swagger UI causes a 422 error."

- "Only accept application/json content-type"

- swagger UI

Result

- Requestbody

- Authroization header

- content-type: application/json, application/x-www-form-urlencoded

Nice! Can you update tests to cover that?

Reflections on the Feedback and Purpose of the PR

After receiving the feedback yesterday, I spent some time reflecting on Airflow's philosophy and current internal structure.
It helped me understand the intention behind the feedback more clearly.

From my perspective, there seems to be a distinction between the authentication mechanisms used for user-facing APIs and those used internally between components within Airflow.

The reason I created this PR was to improve the developer experience for users interacting with the Airflow API through Swagger UI, making it easier to test and trigger endpoints directly.

During this process, I noticed that a 422 Unprocessable Entity error was occurring when using application/x-www-form-urlencoded content type.
To address this, I made a small change to support form-based input without modifying Airflow’s core structure or authentication logic.
The goal was to make the authentication endpoint more user-friendly, especially for those exploring the API via tools like Swagger.

While working on this, I also observed that JWT token handling in Airflow is not yet fully unified across different parts of the system.
I believe this presents an opportunity to submit a follow-up PR that would refactor and unify the token handling logic,
ensuring consistency and paving the way for smoother integration of OAuth2.0 and SSO in the future.

(Note: I drafted my thoughts and structure in Korean first, based on my understanding of the feedback and the current state of the codebase.
ChatGPT helped only with polishing the English writing and markdown formatting — all technical reasoning and intent came from my own review.)

If there's anything I may have misunderstood, I’d really appreciate your clarification.

I'll take some time to read through the AIPs more thoroughly and will reach out again when I'm ready to request a review.
In the meantime, if you have a chance, I’d greatly appreciate it if you could leave your thoughts on the points I mentioned above — your feedback would really help broaden my thinking.

Looks good! Thanks @kyungjunleeme ! Small suggestion to speed up the procedures, please resolve any thread you think you addressed. This can make merging a lot easier since not everyone checking the PR has the full context of all of the threads :)

kyungjunleeme · 2025-07-30T15:30:16Z

@bugraoz93 Thank you, I followed your instructions

jason810496 · 2025-08-01T07:12:29Z

It seems that this PR still needs @ashb's approval before it can be merged.
(Due to GitHub restrictions, if any reviewer has requested changes, the PR requires that specific person's approval to unblock and proceed with the merge.)

Update: I can dismissed review from ash

kyungjunleeme · 2025-08-01T07:49:27Z

Ah ha thank you for telling me! :)

Resolved.
