What happened?

When triggering a DAG from the UI or through the API i get the following error and stacktrace:

  File "/home/airflow/.local/lib/python3.12/site-packages/fastapi/dependencies/utils.py", line 674, in solve_dependencies

    ) = await request_body_to_args(  # body_params checked above

What you think should happen instead?

I expect the dag to be triggered, adding or removing the field from the dag content also does not help

Looks like a duplicate of #56025

[msenmurugan]

@tirkarthi You are right. It seems, the fix is yet to release and also #56025 is not targeted to any release so far.

It was backported and will be available as part of 3.1.1 release. Backport PR #56256
