The function decorated by the "post_load" decorator will undergo changes in parameter types as the function name changes.

Nobody has claimed this yet.

`
class AdGroupUpsertSchemaV3(ma.SQLAlchemySchema):
name = fields.String(required=True)

class Meta:
model = models.AdGroup
fields = 'name'
load_instance = True

@post_load
def a(self, data, *args, **kwargs):
print(type(data))
return data
`

flask-marshmallow==0.14.0
marshmallow==3.17.0
marshmallow-sqlalchemy==0.28.1

like the code above，when post_load decorator func name is a-m, data type is dict, when func name is n-z, data type is

why why why?

The payload names no repository file or test. Reproduce the snippet with flask-marshmallow 0.14.0, marshmallow 3.17.0, and marshmallow-sqlalchemy 0.28.1, then trace post_load handling alongside SQLAlchemySchema and load_instance. A useful resolution would explain why renaming the method changes data's type and add a regression test if the behavior is unintended.
