Data display problem
Briefly

The issue of missing data in your application could stem from improper component rendering. Ensure that each component, including PostItem, is correctly passing and displaying props.
Verify that the DUMMY_POSTS array includes actual posts with all necessary attributes. Check the spread operator in use, as it may inadvertently exclude required data.
Inspect if your rendering logic in Posts.jsx iterates over DUMMY_POSTS correctly, ensuring that each post renders expected output within PostItem or similar components.
If data doesn't display, check console errors for hints or warnings regarding undefined variables or components. This can lead to more insight on rendering issues.
