cannot use func literal (type func(string, string, echo.Context) bool) as type middleware.BasicAuthValidator in argument to middleware.BasicAuth

Question

I want to apply Basic authentication in golang using echo framework. I have following error :

"# command-line-arguments

.\main.go:44:29: cannot use func literal (type func(string, string, echo.Context) bool) as type middleware.BasicAuthValidator in argument to middleware.BasicAuth"

my code:

package main

import (
    "github.com/labstack/echo/v4"
    "github.com/labstack/echo/v4/middleware"
    "net/http"
)


// main function

func main(){
    e := echo.New()

    g := e.Group("/home")

    g.Use(middleware.BasicAuth(func (username, password string, c echo.Context) bool {
        if(username=="iamsns" && password=="Iamsns355@"){
            return true
        } else {
            return false
        }
    
    }))

    g.POST("/login", getHome)
    

    e.Start(":8008")
}

According to the docs middleware.BasicAuthValidator is defined as func(string, string, echo.Context) (bool, error) not func(string, string, echo.Context) bool. You need to change the signature to also return an error.
