python - Scapy: TypeError when adding new protocol/ layer -
I am trying to create a new layer / protocol in the scp. I see this error when I'm trying to send / show it.
I have added breakpoints to see what is happening but somehow the interior is being converted into a string tube. I'm not sure what I'm missing. Can anyone help me in this problem nail?

I used bitfield and had added 3 bits but I was removed from the line which included bitfields with 5 more bits. Because the packet was wrapped by byte in the coalition, there was a complaint. It was good to know that :)
