Derived from the Airflow linter.

This rule is unstable and in preview. The --preview flag is required for use.

What it does

Checks for Airflow function calls that will raise a runtime error in Airflow 3.0 due to function signature changes, such as functions that changed to accept only keyword arguments, parameter reordering, or parameter type changes.

Why is this bad?

Airflow 3.0 introduces changes to function signatures. Code that worked in Airflow 2.x will raise a runtime error if not updated in Airflow 3.0.

Example

from airflow.lineage.hook import HookLineageCollector

collector = HookLineageCollector()
# Passing positional arguments will raise a runtime error in Airflow 3.0
collector.create_asset("s3://bucket/key")

Use instead:

from airflow.lineage.hook import HookLineageCollector

collector = HookLineageCollector()
# Passing arguments as keyword arguments instead of positional arguments
collector.create_asset(uri="s3://bucket/key")
