Traffic Influence via NEF on Free5GC

Hi all,
I deployed a Free5GC v4.0.0 on a fresh Ubuntu 24.04 machine following the instructions on the official documentation.
I am trying to send a request for traffic influence to the NEF using the scripts provided in the free5gc-compose project but the interaction between the NEF and the UDM fails with the attached logs.
The request I am sending, in curl like format, is the following:

curl -X POST -H "Content-Type: application/json" --data @./nef_ti_anyUE.json \
	http://10.30.8.185:8000/3gpp-traffic-influence/v1/af001/subscriptions

Am I doing something wrong?
Thanks in advance

You can find attached the content of the nef_ti_anyUE.json file.nef_ti_anyUE.txt (340 Bytes)

UPDATE:
the traffic influence request works well if the Free5GC is downgraded to v3.4.4.

Hi @l.lossi,

The NEF is currently based on 3GPP Release 15.
We plan to upgrade NEF in free5GC v4.0.1.

You can find our roadmap at: https://free5gc.org/
Please feel free to reach out if you have any further questions.

Best regards,
