Having placeholders "survive" dynamic query building

If the query I'm trying to modify with a dynamic query (....$dynamic()) contains any placeholders, I'm getting an error that says No value for placeholder.... provided.

That seems counterintuitive because I should only be required to provide placeholder values when I actually execute the query, not when I'm still "building" it.

Is this a limitation of Drizzle, or am I thinking the wrong way about this? EDIT: Funny enough, the query seems to still work despite the error..

Simple example to illustrate:

function withPagination<T extends PgSelect>(
  qb: T,
  page: number = 1,
  pageSize: number = 10,
) {
  return qb.limit(pageSize).offset((page - 1) * pageSize);
}

const query = db.select().from(users).where(eq(users.id, sql.placeholder("myPlaceholder"))

const dynamicQuery = query.$dynamic()

withPagination(dynamicQuery, 2, 20) // Error: No value for placeholder "myPlaceholder" was provided


Error: No value for placeholder "myPlaceholder" was provided
