Airflow >= 2.2.0 execution date change is failing TaskInstance get_task_instances method and possibly others #21656

Apache Airflow version

2.2.3 (latest released)

What happened

This is my first time reporting or posting on this forum. Please let me know if I need to provide any more information. Thanks for looking at this!

I have a Python Operator that uses the BaseOperator get_task_instances method and during the execution of this method, I encounter the following error:

This error is from doing an upgrade from airflow 1.10.15 -> 2.2.3.

I am using SQLAlchemy version 1.2.24 but I also tried with version 1.2.23 and encountered the same error. However, I do not think this is a sqlAlchemy issue.

The issue seems to have been introduced with Airflow 2.2.0 (pr: https://github.com/apache/airflow/pull/17719/files), where the TaskInstance.execution_date changed from being a column to this association_proxy. I do not have deep knowledge of SQLAlchemny so I am not sure why this change was made, but it results in it the error I'm getting.

2.2 .0 +

1.10.15

if you follow the stack trace you will get to this chunk of code that leads to the error because the association_proxy has a 'clause_element' attr, but the attr raises the exception in the error when called.
