nullable jsonb failed to specify its struct

[bhscer]

Version

1.29.0

What happened?

The doc https://docs.sqlc.dev/en/stable/reference/datatypes.html#json says that we can specify the struct to a jsonb, but I tried to make a easy demo of doc's code and failed.

The generated model is

type Book struct {
	ID   int32
	Data types.BookData
}

but the doc says that will be

type Book struct {
    Data *dto.BookData
}

This problem also happens in EditBookParams, I have provide the playground url: https://play.sqlc.dev/p/b1e8f0509a8d5c4e13f18db4b738040590eb1debc7439b4169314568d72e7742

Relevant log output

Database schema

CREATE TABLE books (
    id SERIAL PRIMARY KEY,
    data jsonb
);

SQL queries

-- name: GetBookById :one
SELECT * FROM books
WHERE id = @id LIMIT 1;
