confusing return type of `select`

When I use

select

select

, I encounter type errors because the return type is identical. I am confused about why we must return the data shape if there's no need for using

select

select

/**
 * This option can be used to transform or select a part of the data returned by the query function.
 */
select?: (data: TQueryData) => TData;

/**

 */
select?: (data: TQueryData) => TData;
