QueryHelperResult doesn't accept helper with optional argument

[IlyaSemenov]

QueryHelperResult doesn't accept helper with optional argument:

import { type QueryHelperResult, createBaseTable, orchidORM } from "orchid-orm"

const BaseTable = createBaseTable()

class PostTable extends BaseTable {
  readonly table = "post"

  columns = this.setColumns(t => ({
    id: t.identity().primaryKey(),
    text: t.text(),
  }))
}

const db = orchidORM({}, { post: PostTable })

const selectPost = db.post.makeHelper((q, searchTerm?: string) =>
  q.where(q => searchTerm ? q.whereSql`text like ${`%${searchTerm}%`}` : q),
)

// Type 'unknown' is not assignable to type 'string | undefined'.
export type Post = Awaited<QueryHelperResult<typeof selectPost>>[0]

Interestingly though, this works:

const selectPost = db.post.makeHelper((q, searchTerm = "") =>
  q.where(q => searchTerm ? q.whereSql`text like ${`%${searchTerm}%`}` : q),
)

// No type errors
export type Post = Awaited<QueryHelperResult<typeof selectPost>>[0]
