Nested Generics don't resolve inner type properly

[theelderbeever]

The following code shows the response as { data: string, error: string } in Swagger instead of resolving the inner struct.

#[derive(OpenApi)]
#[openapi(
    paths(get_usage),
    tags((name = "Account Usage")),
    components(schemas(crate::api::v1::usage::schemas::Window, JsonAccountUsage, AccountUsage))
)]
pub struct ApiDoc;

#[derive(Serialize, Deserialize, Debug, ToSchema)]
#[aliases(JsonAccountUsage = JsonResponse<AccountUsage>)]
pub struct JsonResponse<T>
where
    T: Serialize,
{
    pub data: Option<T>,
    pub error: Option<String>,
}

#[derive(Debug, FromQueryResult, Serialize, Deserialize, ToSchema)]
pub struct AccountUsage {
    #[serde(with = "services::serde::time")]
    pub window_start: OffsetDateTime,
    #[serde(with = "services::serde::time")]
    pub window_end: OffsetDateTime,
    pub account: Uuid,
    pub instance: Option<Uuid>,
    pub method: Option<String>,
    pub archive: Option<bool>,
    pub chain: Option<String>,
    pub network: Option<String>,
    pub addon: Option<i32>,
    pub multiplier: Option<i32>,
    pub usage: i64,
    pub credits: i64,
}

#[utoipa::path(
    get,
    path = "/{account}/usage",
    responses(
        (status = 200, body = BillingAccountUsage),
    ),
    tag = "Account Usage",
    params(
        ("account" = Uuid, Path, description = "Account UUID"),
        AccountUsageParams,
    )
)]
pub async fn get_usage(

@theelderbeever There is now new implementation for generics coming up in #1034 which should solve the issue with aliases approach.
