Description

• Updated the ElectricBill dataclass to allow the last_date_to_pay field to be None by using Optional typing and setting a default value of None.
• Modified the ResponseDescriptor and ResponseWithDescriptor dataclasses to set default values of None for code, description, and data fields, enhancing the flexibility of these models.

Here are some key observations to aid the review process:

⏱️ Estimated effort to review: 2 🔵🔵⚪⚪⚪

🧪 No relevant tests

🔒 No security concerns identified

⚡ Recommended focus areas for review Data Validation The last_date_to_pay field is now optional but there's no validation logic to handle None values in downstream code that may expect a valid date string Code Organization The data field is moved after response_descriptor which may affect serialization order. Consider keeping consistent field ordering

PR Code Suggestions ✨

Explore these optional code suggestions:

Category	Suggestion	Score
General	Use appropriate date type instead of string for date fields to ensure proper date handling and validation The last_date_to_pay field is defined as Optional[str], but since it represents a date, it should use a more appropriate type like Optional[datetime] or Optional[date] to ensure proper date handling and validation. iec_api/models/electric_bill.py [52] -last_date_to_pay: Optional[str] = field(metadata=field_options(alias="lastDateToPay"), default=None) +last_date_to_pay: Optional[datetime] = field(metadata=field_options(alias="lastDateToPay"), default=None) Apply this suggestion Suggestion importance[1-10]: 7 Why: Using datetime instead of str for date fields is a good practice that enables proper date validation and manipulation. This change would improve type safety and make the code more maintainable.	7
	Place optional fields after required ones in dataclass definitions for better code organization The data field should be placed before response_descriptor to maintain a logical order where optional fields come after required ones, following Python's dataclass best practices. iec_api/models/response_descriptor.py [37-38] +data: Optional[T] = None response_descriptor: ResponseDescriptor = field(metadata=field_options(alias=RESPONSE_DESCRIPTOR_FIELD)) -data: Optional[T] = None Apply this suggestion Suggestion importance[1-10]: 3 Why: While the suggestion follows Python's dataclass best practices, the current field order doesn't significantly impact functionality or maintainability. The improvement is mainly cosmetic.	3

No reason for setting default values, they'll be None by default

[SL1994-design]

I had some errors without this added line. for example: errorMessage": "Field \"response_descriptor\" of type ResponseDescriptor in ResponseWithDescriptor has invalid value {'isSuccess': True, 'code': '00'}",

[GuyKh]

When trying to parse the response:

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "<string>", line 6, in __mashumaro_from_dict__
mashumaro.exceptions.MissingField: Field "data" of type Optional[Any] is missing in ResponseWithDescriptor instance

This means that data field (and not code) can be None.
Which you already added.
