List index out of range error when canceling filechooser in Kivy

I tried to make this video uploading app to my firebase storage, but I'm stuck at this problem. When the upload button is pressed, the filechooser is opened and if i select a file, it gets uploaded to firebase. But if i cancel and close the filechooser, it gives an error:

Traceback (most recent call last): File "C:\Users\Dheeraj\AppData\Roaming\Python\Python38\site-packages\plyer\platforms\win\filechooser.py", line 108, in run self._handle_selection(self.selection) File "C:\Users\Dheeraj\Desktop\kivy codes\Dheeraj.py", line 949, in selected Directory=selection[0] IndexError: list index out of range [INFO ] [Base ] Leaving application in progress...

I am unaware if this file chooser works on android or not. If it does not, please help me with this code too.

i think i've figured it out all i have to do was indent the code of selected function under its own if selection==True statement. thanks to everyone who tried to help 🙏.

New Code

def selected(self,selection):
    
    if selection==true:
        self.root.ids.vid.source=firebase
        configure={
        'apiKey': "**confidential**",
        'authDomain': "**confidential**",
        'databaseURL': "**confidential**",
        'projectId': "**confidential**",
        'storageBucket': "**confidential**",
        'messagingSenderId': "**confidential**",
        'appId': "**confidential**",
        'measurementId': "**confidential**",
        'serviceAccount':"**confidential**",
        'databaseURL':'**confidential**' 

                  }
    firebase=pyrebase.initialize_app(configure)
    storage=firebase.storage()            
    Directory=selection[0]
    Name=re.findall('[ \w-]+\..*',Directory)
    storage.child(str(f"{Name}")).put(str(f"{Name[0]}"))
