[BUG] new key "dataclass_json_config": null #506

Open navimac opened 5 months ago

navimac commented 5 months ago

Description

when serializing object with dataclasses-json==0.6.2 I get new key "dataclass_json_config": null, which ruins my serialization and was not present in version 0.6.1 I reverted the change dataclass_json_config: Optional[dict] = None to dataclass_json_config = None and now I don't get this extra key.

Code snippet that reproduces the issue

code is under NDA but basically we use asdict method and then we pass this to a json.dumps method. We also allow that keys can be null

Describe the results you expected

Json file without "dataclass_json_config": null key, value pair

Python version you are using

Python 3.9.16.1

@george-zubrienko I created the issue. I can't post part of the code directly but I have described the basic usage. I hope this is ok
