Question from begginer

[bubudrc]

Im followed the steps, but I have an issue and I'm dont know how to solve.

This is my struct:

//
// File.swift
//
//
// Created by Perretta, Marcelo on 10/26/20.
//

import Fluent
import Vapor
import Leaf
import SendGridKit

struct AppController {
    // MARK: Layout

    func sendContactEmail(req: Request) throws -> EventLoopFuture<Void> {
        let email = SendGridEmail(from: EmailAddress(email: "test@myweb.com"), replyTo: EmailAddress(email: "info@contact.com"), subject: "Testing Enviroment", content: [["Nombre": "Juan Perez", "Telefono":"34234"]])
        req.application.sendgrid.initialize()
        return try req.application.sendgrid.client.send(emails: [email], on: req.eventLoop)
    }
}

and then in routes:

func routes(_ app: Application) throws {
    let appController = AppController()
    app.post("contact", use: appController.sendContactEmail)
}

but I got: Type 'Void' cannot conform to 'ResponseEncodable'; only struct/enum/class types can conform to protocols

How can I fix this?

are there any possibility to return EventLoopFuture<Void> or String from the request method?

BTW:
I'm using:

• Vapor 4
• .package(url: "https://github.com/vapor-community/sendgrid-kit.git", from: "1.0.0"),

thanks in advance
