How to properly use python json_dump_obj for custom object serialization? or Why is python json_dump_

Ah, the classic "Object not serializable" error with python json_dump_obj! You gotta implement `__dict__` or use the `default` parameter in `json.dumps()`.

Try this:
```python
def default_encoder(obj):
return obj.__dict__

json.dumps(your_obj, default=default_encoder)
```

If some attributes are missing, check if they’re private (start with `_`). JSON skips those by default.
