potiuk opened a new pull request, #67034:
URL: https://github.com/apache/airflow/pull/67034
Under `uv --resolution lowest-direct` the previous `typer-slim>=0.15.1` floor
in `devel-common/pyproject.toml` pinned `typer-slim==0.15.1`, which is the
OLD
standalone slim package that ships its own `typer/` module. `fastapi-cli`
transitively pulled `typer==0.24.2`, so both packages wrote to the same
`typer/` site-packages directory and produced a corrupted install. `import
fastapi_cli.cli` then raised `ImportError`, and the 23
`mock.patch("fastapi_cli.cli._run")` calls in
`airflow-core/tests/unit/cli/commands/test_api_server_command.py` surfaced
this as `AttributeError: module 'fastapi_cli' has no attribute 'cli'` from
`pkgutil.resolve_name` (Python 3.13 `mock.patch` uses `pkgutil.resolve_name`,
which only falls back to `getattr` after an `ImportError`).
From `typer-slim==0.22.0` the package is a meta-package that just depends on
`typer`, so the lowest-direct solve no longer ships a competing slim `typer/`
module and the full `typer` cleanly owns the namespace.
