How to send data to endpoint when running tests?

[Glitchy-Tozier]

I've started working on automated tests. However, when trying to send data to an enpoint, I couldn't find a way to do so without rust complaining.

How can I send data = "<setup_data>" to this path?

Endpoint:

#[post("/create", format = "json", data = "<setup_data>", rank = 3)]
fn create_poll(conn: DbConn, setup_data: Json<SetupData>) -> ApiResult<String> {
   ...
}

I tried this:

But Rust complains:

Using .json(data) instead of .body(Json(data)) fixed the issue.
