   This is an odd one:
   
   ```
   E   sqlalchemy.exc.ArgumentError: Type annotation for 
"TaskInstance.dag_model" can't be correctly interpreted for Annotated 
Declarative Table form.  ORM annotations should normally make use of the 
``Mapped[]`` generic type, or other ORM-compatible generic type, as a container 
for the actual type, which indicates the intent that the attribute is mapped. 
Class variables that are not intended to be mapped by the ORM should use 
ClassVar[].  To allow Annotated Declarative to disregard legacy annotations 
which don't use Mapped[] to pass, set "__allow_unmapped__ = True" on the class 
or a superclass this class. (Background on this error at:
