When running the packet sniffer, I continue to getting multiple errors stating the following:
Traceback (most recent call last):
File “/usr/lib/python3/dist-packages/scapy/packet.py”, line 372, in __getattr__
fld, v = self.getfield_and_val(attr)
TypeError: cannot unpack non-iterable NoneType objectThe other error said the following:
During handling of the above exception, another exception occurred:Traceback (most recent call last):

AttributeError: hasLayerAny help you can provide would be appreciated. I’ve attached my code as well.
Hi!
You have used a capital L in haslayer and that’s a wrong syntax, check Zaid’s code and make sure yours is exactly the same, especially pay attention to the syntax.
Greetings!
DiegoThanks for your continued help, Diego. It seems now I’m getting the following error around the Raw field (see message below). I’ve also attached my code as it’s been written exactly as Zaid or so I thought when I checked it again.
