Related object is not typed correctly

I have the following schema

export const menus = pgTable('menus', {
  id: uuid('id').primaryKey(),
  name: varchar('name', { length: 256 }).notNull(),
});

// categories 
export const categories = pgTable('categories', {
  id: uuid('id').primaryKey(),
  name: varchar('name', { length: 256 }).notNull(),
  menuId: uuid('menu_id').references(() => menus.id),
});

export const menuCategories = relations(menus, ({ many, one }) => {
  return {
    categories: many(categories)
  };
});

And I am querying like this

async function main(){
    const res = await db.query.menus.findMany({
        with:{
            categories:true
        }
    })

    const cat = res[0].categories[0]
}

cat is of type

{
  [x:string]:any
}

I was expecting it to be typed correctly

you need to pass your schema into drizzle() as the second argument

import * as schema from "./schema"
export const db = drizzle(connection, { schema })

@Kairu I am already doing that, everything is exported from the same place so I know it's not missing

you need to define the reverse relation side, otherwise, there is no way to know which columns define this relation

@Dan Kochetov do I always have to define both sides of the relation? What if I only ever want to query from one side?

not always, but in this case you didn't specify the columns

Can I just specify the fields in the many relation?

I'm just gonna write some helper functions to automatically generate it, I hope I can make it type safe though

you need to define the columns on the relation side that actually has those columns
the many side doesn't have columns that define the relation
