Static type checker info
Expression of type "Dict[str, Any] | None" cannot be assigned to declared type "dict[str, list[str]]"
Type "Dict[str, Any] | None" cannot be assigned to type "dict[str, list[str]]"
"None" is incompatible with "dict[str, list[str]]"
Code snippet
import json
from aws_lambda_powertools.event_handler.router import ALBRouter
router = ALBRouter()
@router.get("/")
def get_headers() -> str:
headers: dict[str, list[str]] = router.current_event.resolved_headers_field
return json.dumps(headers)
### Possible Solution
Remove `Optional`
```diff
- def resolved_headers_field(self) -> Optional[Dict[str, Any]]:
+ def resolved_headers_field(self) -> Dict[str, Any]:
