Issue Description

When I use srsUE with srsRAN gnb and Open5GS and I add a PCC rule, the srsUE at NR Connection Reconfiguration finishes with a failure.

Setup Details

[Specify details of the test setup. This would help us reproduce the problem reliably] e.g. Network configuration, Operation System, Hardware, RF front-end, library and driver versions I am using the UHD driver for RF connection between two b210 usrps connected by wires with a 30 dB attenuator. My config files and logs are attatched below. logsandconfs(2).zip The Open5GS config is show in this figure:

The srsue commit used is the last one from the main branch and the srsgnb used is the last one from the test branch.

Expected Behavior

I expect the UE adds the new QFI.
