// ways to make the file uploading work on the poroduction
// create FILE_MAIN_URL in .env file and assign it with the following values
// a, https://localhost:3000/  for local development and then switch it to
// b, https://fmcms-demer-trading.herokuapp.com/ for production
// THEN after all add the process.env.FILE_MAIN_URL before the file URL as follow
// {`process.env.FILE_MAIN_URL${business.TL_Image}`}
// And before everything the file has to be configured to be uploaded in to the./uploads folder
