Files that have an uppercase letter in their filename are not served. My file structure:

- [project root]
    - main.go
    - public
        - js
            - A.js

Expected behavior
The file should be sent to the client

2.) Run the code below
3.) Send request to /js/<filename>.js

Code snippet

package main

import "github.com/gofiber/fiber"

  app.Static("/js", "./public/js")
  app.Listen(3000)
}
