golang echo controller model

I am getting the following error when trying to factory my controller:

cannot use &(personController literal) (value of type *personController) as PersonController value in return statement: wrong type for method CreateNewPerson (have func(ctx github.com/labstack/echo/v4.Context) error, want func(ctx github.com/labstack/echo/v4.Context))

controller:

package controllers

import (
    "net/http"

    "github.com/labstack/echo/v4"
)

type personController struct{}

var (
// services
)

type PersonController interface {
    CreateNewPerson(ctx echo.Context)
    GetPerson(ctx echo.Context)
}

func NewPersonController() PersonController {
    return &personController{}
}

func (*personController) CreateNewPerson(ctx echo.Context) error {
    return ctx.JSON(http.StatusOK, "Hello")
}

func (*personController) GetPerson(ctx echo.Context) error {
    return ctx.JSON(http.StatusOK, "Hello")
}

and in my main func ai got this error :

func main() {
    e := echo.New()
    controller := controllers.NewPersonController()
    e.POST("/a", controller.CreateNewPerson)
}

cannot use controller.CreateNewPerson (value of type func(ctx echo.Contex

Your interface and struct implementation don't match. If you want your interface method's to match what's required by the echo framework then do this:

type PersonController interface {
    CreateNewPerson(ctx echo.Context) error
    GetPerson(ctx echo.Context) error
}
