Describe the bug
Hi, after implementing the sandbox in a virtual machine, when I use the internet forwarding feature i get the following error:

cuckoo.processing.errors.PluginError: Failed to run plugin Pcapreader. 'int' object has no attribute 'type'

To Reproduce
I am using the cuckoorooter feature enabling the forwarding in Internet.
Terminal 1: cuckoorooter -g pcap --debug
Terminal 2: cuckoo --debug
Also i'm testing it with an eicar file, this one https://www.eicar.org/download/eicar-com-2-2/?wpdmdl=8848&refresh=67977acc80ae71737980620.

Edit:
if I use the "drop" function I don't get any errors, but if I use the "Internet" function i get them.

Expected behavior
That it completes the analysis and does not return any errors to me

** My Cuckoo version and operating system are::**
Cuckoo 3.0.1, Ubuntu 22.04.5 LTS

@xMarf Thank you for reporting the issue.
Unfortunately, we have not had this error before, we are investigating what could have caused it.

I also faced this problem when network is enabled. self.recv holds an int instead of some object with .type ..

It happens both at decrypt_client and decrypt_server ...

I have the problem only if I use the "Internet" function, the network configuration is enabled and if I use the "Drop" function there are no problems.
I also noticed that all the methods called have the ts parameter in common, could the configuration have something to do with it?
