upg-vpp: 5G PFCP Error

Hi,

Please I am trying to setup upg-vpp as UPF for open5gs SMF.

The error I get from the open5gs SMF is:

After a while upg-vpp crashes…

Steps that I used in installing upg-vpp:

cd /usr/src
git clone https://github.com/travelping/upg-vpp
cd upg-vpp
make update-vpp
cd vpp
make install-deps
make install-ext-deps
make build

Also it will be great if someone can point me to where the documentation is, I was unable to locate this in this repo.
