Unable to create macro for route generation

[sahilarora3117]

Hi, I have many similar functions that needs to run on multiple paths. I wanted to create a macro so that i can define the routes in a faster manner.

macro_rules! episodes {
    ($name:ident, {$($arg:ident: $ty:ty),*}, $attr:literal) => {
        #[get($attr)]
        pub async fn $name(cache: &State<RedisCache>, client: &State<Client>, base_url: &State<String>, $($arg: $ty),*) -> status::Custom<Json<Vec<serde_json::Value>>> {
            let params = uri!($name($($arg),*)).to_string();
            fetch_data(cache, client, base_url, params, constants::SERIES_TTL).await
        }
    };
}

episodes!(episodes, {page: Option<u64>}, "/episodes?<page>");
episodes!(episodes_id, {id: u64}, "/episodes/<id>");
episodes!(episodes_id_extended, {id: u64}, "/episodes/<id>/extended");
episodes!(episodes_id_translations, {id: u64, language: String}, "/episodes/<id>/translations/<language>");

The bottom 3 works but the top one fails because of a weird reason, am i doing something wrong?

error[E0425]: cannot find value `__rocket_page` in this scope
  --> src/api/episodes.rs:20:22
   |
20 | episodes!(episodes, {page: Option<u64>}, "/episodes?<page>");
   |                      ^^^^ not found in this scope

I believe this has something to do with "?"
I just started out with rust, so any help would be useful
