poem-openapi: operation_id doesn't work with transform

[DDtKey]

Expected Behavior

I want to specify operation_id& add transform to my endpoint.
The code below should work fine:

struct Api;

#[OpenApi]
impl Api {
    #[oai(path = "/hello", method = "get", operation_id = "hello", transform = "my_transformer")]
    async fn index(&self) -> PlainText<String> {
        PlainText(format!("hello, world!"))
    }
}

fn my_transformer(ep: impl Endpoint) -> impl Endpoint {
    ep.with(MyMiddleware::new())
}

Actual Behavior

It returns error:

error[E0599]: no method named `set_data` found for mutable reference `&mut <impl poem::Endpoint as poem::Endpoint>::Output` in the current scope

| #[OpenApi]
| ^^^^^^^^^ method not found in `&mut <impl poem::Endpoint as poem::Endpoint>::Output`

Looks like it was broken after #351
It perfectly works on poem-openapi 2.0.7

Specifications

• Version: poem: 1.3.45 + poem-openapi: 2.0.15
