barking-code opened a new issue, #40617:
URL: https://github.com/apache/airflow/issues/40617
### Apache Airflow version
Other Airflow 2 version (please specify below)
### If "Other Airflow 2 version" selected, which one?
2.9.0
### What happened?
After updating to Airflow 2.9.0 from 2.6.2, I met a mypy error like the one
below.
`Incompatible types in assignment (expression has type "Column[Integer]",
variable has type "int")`
So, I tested some simple code, it raised the same error.
This code makes an `Incompatible` error on `2.9.0`, not `2.6.2`.
I used `sqlalchemy2-stubs==0.0.2a38` and `mypy==1.5.0` in both versions. And
mypy.ini included `plugins = sqlalchemy.ext.mypy.plugin`
```python
from airflow.models import Base
from sqlalchemy import Column, Integer
class Tester(Base):
col1 = Column(Integer(), primary_key=True)
i: int = Tester.col1
```
