Gin BasicAuth middleware not working

Description

BasicAuth doesn't work.

How to reproduce

This is demo code, main.go

package main

import (
    "github.com/gin-gonic/gin"
)

func main() {
    router := gin.Default()

    authorized := router.Group("/", gin.BasicAuth(gin.Accounts{
        "user": "pass",
    }))

    authorized.Static("/", string("./"))

    router.Run()
}

Also add an index.html at root directory to test access, same level with main.go.

then run the app:

go run main.go

Expectations

• When accessing on browser at http://localhost:8080/index.html, it expects to show the Basic Auth request dialog to authenticate.

Actual result

Browser responds ERR_TOO_MANY_RETRIES, and server logs return tons of these responses:

[GIN] 2022/06/18 - 00:12:48 | 401 |       5.167µs |             ::1 | GET      "/"

Environment

• go version: go1.18.3 darwin/arm64
• gin version (or commit ref): github.com/gin-gonic/gin v1.8.1
• operating system: MacOS 12.4 / MacBook Pro (16-inch, 2021) Apple M1 Max

Additional Info

the code works fine if removing the BasicAuth middleware

    authorized := router.Group("/")
