Issue replacing images

[mardelnet]

Hello everyone!
I am working on implementing a custom file replacement feature for my project.
So far, I can replace correctly both locally and in the Google Storage cloud any file except images.
When it comes to images, only the original file is replaced, but not the rest of the image sizes.
This is the piece of code I'm using to fire the replacement in Google Storage:

$attach_data = wp_generate_attachment_metadata($old_file_id, $old_file_path);
$post_meta_updated = wp_update_attachment_metadata($old_file_id, $attach_data);

Has anyone faced a similar situation?
