You can [cast](https://mypy.readthedocs.io/en/stable/type_narrowing.html#casts) the result of the expression to the desired type

```py
def load_json_data(filepath: str) -> Dict[str, Any]:
    with open(filepath) as json_data:
        return cast(Dict[str, Any], json.load(json_data))
```

You can also just ignore the error

```py
def load_json_data(filepath: str) -> Dict[str, Any]:
    with open(filepath) as json_data:
        return json.load(json_data) # type: ignore[no-any-return]
```
