Hello! I am struggling to check whether the compilation is correct by running ./build/tests/registration/registration.

SCTP is running fine, Mongodb is active and my nrf.yaml dose match with amf.yaml.
Tried different versions up to v2.4.15 with no success.
I have no errors checking the EPC with ./build/tests/attach/attach
What am I doing wrong?
