Inferred Types not picking up Relations

I'm having issues with my inferred types from the "Core Type API" not picking up relations.

I am trying to model a 1-to-Many relationship between users and assignments . A user can "create many" assignments. My query looks like this:

await client(context.env.DB).query.assignmentsTable.findMany({
        with: {
          createdBy: true
        },
      });


And the involved tables and relations from my schema file are defined as:

export const assignmentsTable = sqliteTable("assignments", {
  id: integer("id", { mode: "number" }).primaryKey({ autoIncrement: true }),
  position: text("position").notNull(),
  // ...other columns
  createdBy: integer("created_by")
    .references(() => usersTable.id, { onDelete: "cascade" })
    .notNull(),

export const assignmentsRelations = relations(
  assignmentsTable,
  ({ one, many }) => ({
    // 1 assignment is created by 1 user
    createdBy: one(usersTable, {
      fields: [assignmentsTable.createdBy],
      references: [usersTable.id],
      relationName: "assignments.created",
    }),
  }),
);

export const usersTable = sqliteTable("users", {
  id: integer("id", { mode: "number" }).primaryKey({ autoIncrement: true }),
  userId: text("user_id").notNull(),
  last: text("last").notNull(),
  first: text("first").notNull(),
  // ...other columns
});

export const usersRelations = relations(usersTable, ({ many }) => ({
  assignmentsCreated: many(assignmentsTable, {
    relationName: "assignments.created",
  }),
  // ...other relations
}));


My type is defined as:
export type Assignment = typeof assignmentsTable.$inferSelect;


The query properly retrieves the user under the createdBy column but the typing still thinks the createdBy column should be a number and not the embedded user from the relation. What am I missing here?
