PDU Session Establishment Failure in UERANSIM after merge of snssai_w_wo_ox branch
I'm unable to establish a PDU session with UERANSIM. The connection initialises correctly but fails during the PDU Session Establishment phase with an authentication error.

- The issue appears to have been introduced after the merge of branch 'snssai_w_wo_ox' into 'develop'
- I verified the issue exists in MR 285 (selfix.sboai.cs.eurecom.fr/oai-smf:ci-tmp-pr-285-cda5a6ba)
- I'm using v2.1.9 tags for the affected images and 'develop' tags for the rest and it works, change the v2.1.9 tags to develop produces the error.
- I've tested with both UERANSIM v3.26 and v3.2.7 with the same results

I've attached my docker-compose file and UERANSIM configuration files for reference and to help with troubleshooting. I have also attached the container logs and pcap file. You can also use the branch
