            return print(er)
        }

        let fileRef = storageRef.baby(path)
        
       
        let uploadTask = fileRef.putData(imageData!, metadata: nil) {metaData, error in
            print("THIS: from uploadTAsk")
           
            if error == nil && metaData != nil {

                    if let err = error {
                        print(err.localizedDescription)
                        return
                    }
                    
                    guard let validUrl = url else {
