openapi function not found

[squadgazzz]

Once #[utoipauto(paths = "./crates/solvers-dto/src/auction.rs from solvers-dto")] is added, I have a compilation error:

31 |     println!("{}", ApiDoc::openapi().to_yaml().unwrap());
   |                            ^^^^^^^ function or associated item not found in `ApiDoc`

source code:

use utoipa::OpenApi;
use utoipauto::utoipauto;

mod pet_api {

    /// Get pet by id
    ///
    /// Get pet from database by pet id
    #[utoipa::path(
    get,
    path = "/pets/{id}",
    responses(
    (status = 200, description = "Pet found successfully", body = Pet),
    (status = NOT_FOUND, description = "Pet was not found")
    ),
    params(
    ("id" = u64, Path, description = "Pet database id to get Pet for"),
    )
    )]
    async fn get_pet_by_id(pet_id: u64) -> Option<solvers_dto::auction::Auction> {
        None
    }
}

#[utoipauto(paths = "./crates/solvers-dto/src/auction.rs from solvers-dto")]
#[derive(OpenApi)]
#[openapi(paths(pet_api::get_pet_by_id))]
struct ApiDoc;

pub fn main() {
    println!("{}", ApiDoc::openapi().to_yaml().unwrap());
}

Do I miss something? Removing utoipauto and reverting back to the pure utoipa fixes the issue and the code works fine.
