Go Echo: POST Method gives Error "Method not allowed"

Building an app with echo and basically created some routes. The GET ones are working fine, but the post one is give me the error: Do not really understand where the error lies here.

{...."method":"GET","uri":"/addPerson", message=Method Not Allowed","...."bytes_in":0,"bytes_out":33}

main.go snippet

    func initEchoServer() {
    e := echo.New()
    e.Use(middleware.Logger())
    e.Use(middleware.Recover())
    // get all persons
    e.GET("/persons", Info)
    // get specific id
    e.GET("/persons/:id", getPerson)

    e.POST("/addPerson", addPerson)
    e.Logger.Fatal(e.Start(viper.GetString("port")))
}

func addPerson(c echo.Context) error {
    ctx := context.Background()
    db, err := sql.Open("postgres", "host=postgres port=5432 user=postgres dbname=postgres password=postgres sslmode=disable")
    if err != nil {
        log.Fatal(err)
    }
    queries := postgres.New(db)
    insertedPerson, err := queries.CreatePersons(ctx, postgres.CreatePersonsParams{
        Firstname: "Mike",
        Lastname:  "Jordan",
    })
    if err != nil {
        log.Errorf("Failed to insert a person %v", err)
        return err
    }
    fmt.Println(insertedPerson)
    return c.JSONPretty(http.StatusOK, insertedPerson, "  ")
}

queries.sql.go snippet

type CreatePersonsParams struct {
    Firstname string
    Lastname  string
}

func (q *Queries) CreatePersons(ctx context.Context, arg CreatePersonsParams) (Person, error) {
    row := q.db.QueryRowContext(ctx, createPersons, arg.Firstname, arg.Lastname)
    var i Person
    err := row.Scan(&i.ID, &i.Firstname, &i.Lastname)
    return i, err
}

you're use post method in routers

e.POST("/addPerson", addPerson)

You can use postman to hit API using POST method, don't use browser
