SelectObjectContent object has invalid logical size {size}

Error message

SelectObjectContent object has invalid logical size {size}

What it means

PrepareSelectObjectSnapshotError::InvalidSize: the object's logical size recorded in metadata is not usable for snapshotting (e.g. negative or nonsensical), so ranges over it cannot be trusted; indicates corrupted metadata.
