I have a Marshmallow Schema defined as:
class MySchema:
myfield = fields.Str(required=False, default=“value”)
When I do:
s = MySchema().load({})
I would expect the return to be: {‘myfield’:’value’}
But I am getting {} in return.
Is there anything am I missing?
Edit:
I’m using marshmallow 3.11 due to project limitations. I can’t upgrade to 3.15. Tried with 3.15 and it is working as expected.

Until marshmallow 3.12:
default: value to use by default when dumping (serializing)missing: value to use by default when loading (deserializing)
Since marshmallow 3.13:
dump_default: value to use by default when dumping (serializing)load_default: value to use by default when loading (deserializing)
default / missing still behave the same in marshmallow 3.13+ but issue a deprecation warning.
