Sounds like your file might not be flushing properly! json.dump doesn’t *always* write immediately—especially if the program crashes or exits weirdly.

Either:
- Manually `f.close()` after json.dump, or
- Use `with` blocks (they’re magic).

If the file’s empty, check permissions too. And if it’s garbage, your data’s probably not JSON-friendly. Tools like `pydantic` can help validate data before dumping.
