### Under which category would you file this issue? Airflow Core ### Apache Airflow version main ### What happened and how to reproduce it? **Issue Description** The `__getattr__` fallback in `airflow.utils.helpers` is designed to provide backward compatibility for deprecated functions that have moved (like `render_template_as_native`). However, it currently fails and throws an `AttributeError` when any of those functions are accessed. This happens because the fallback dynamically loads the new module using `__import__(modpath)`. When `modpath` is a dotted path (e.g., `"airflow.sdk.definitions.context"`), Python's `__import__` without the `fromlist` argument returns the root package (`airflow`), not the leaf module. The subsequent `getattr` call then tries to find the function on the root `airflow` module, which fails. **Steps to reproduce:** Run the following in a Python shell: ```python import airflow.utils.helpers # Attempt to access a deprecated function that has moved to a dotted module path airflow.utils.helpers.render_template_as_native ``` This incorrectly produces the following error: AttributeError: module 'airflow' has no attribute 'render_template_as_native' ### What you think should happen instead? Instead of raising an `AttributeError`, the `__getattr__` fallback should properly resolve the leaf module, trigger the `DeprecationWarning`, and return the requested function. This can be easily fixed by using `importlib.import_module(modpath)` instead of `__import__(modpath)`. *(Note: I already have a PR ready to submit for this fix!)* ### Operating System Not Applicable ### Deployment None ### Apache Airflow Provider(s) _No response_ ### Versions of Apache Airflow Providers Not Applicable ### Official Helm Chart version Not Applicable ### Kubernetes Version Not Applicable ### Helm Chart configuration Not Applicable ### Docker Image customizations Not Applicable ### Anything else? _No response_ ### Are you willing to submit PR? - [x] Yes I am willing to submit a PR! ### Code of Conduct - [x] I agree to follow this project's [Code of Conduct](https://github.com/apache/airflow/blob/main/CODE_OF_CONDUCT.md) -- This is an automated message from the Apache Git Service.
