hello can anyone why this code does not work

self.sun = loader.loadModel("models/planet_sphere")
        self.sun.reparentTo(render)
        
        self.box = loader.loadModel("models/box")
        self.box.reparentTo(render)
        self.box.setPos(0, 0, 0)
        
        audio3d = Audio3DManager.Audio3DManager(base.sfxManagerList[0], self.box)
        audio3d.attachListener(self.box)    
        
        self.loop = audio3d.loadSfx("SFXmusic/sonic.wav")
        self.loop.setLoop(True)
        audio3d.attachSoundToObject(self.loop, self.sun)
        self.loop()

this is the message i get form my terminal

I don’t understand because the object is in reference to Audio3DManage with a . ie Audio3DManager. which is followed by the identifier and that is followed by the expression (base.sfxManagerList[0])
so this should work but does not why?
do I have to change the identifier or expression?

The code you have posted is not the one which creates the error message. Pay attention to upper and lower case letters!
Here is (relevant part of) the traceback you posted:

    audio3d = Audio3DManager.audio3DManager(base.sfxManagerList[0], self.box)
