Enabling EAP-AKA' both 5G and wifi using free5GC AUSF

Hello all,

I am working on enabling EAP-AKA’ both 5G and wifi using free5GC AUSF.
So a UE is connecting to a wifi AP and the AP is sending an authentication message to AUSF.

When I tried to connect a UE from wifi AP to AUSF using EAP-AKA’, I got the following error. Could you please look at those errors and let me know if you know the reason if you have any moment. I didn’t modify any code in AUSF so it’s an original code from the official source. Thank you in advance.
