Example:

from minos.common import (
    DeclarativeModel,
)


class Inventory(DeclarativeModel):
    amount: int = 0
    reserved: int = 0
    sold: int = 0

Current error message:

self = <minos.common.model.serializers.avro_data_decoder.AvroDataDecoder object at 0x103a531f0>
type_field = <class 'int'>
data = <class 'minos.common.model.types.data_types.MissingSentinel'>

    def _cast_single_value(self, type_field: Type, data: Any) -> Any:
        if type_field is NoneType:
            return self._cast_none_value(type_field, data)
    
        if data is None:
            raise MinosReqAttributeException(f"{self._name!r} field is '{None!r}'.")
    
        if data is MissingSentinel:
>           raise MinosReqAttributeException(f"{self._name!r} field is missing.")
>           minos.common.exceptions.MinosReqAttributeException: 'reserved' field is missing.

I agree with you @vladyslav-fenchak, this is an interesting feature we should implement in the future!
