slicing file not able to parse in gNB

[27-Parth]

I am trying to implement network slicing using the open5Gs core network, and after doing the required changes in the network function files, I tried to change the configuration files srsRAN (gnb_zmq.yaml), I am using an external USRP to implement the gNodeB. This is the error which I encountered after doing the changes in the gnb file, I tried reverting back the changes but as I have changed the network functions, so that also won't work.

This is the error

**iisst@iisst:~/srsRAN_Project/build/apps/gnb$ sudo ./gnb -c gnb_zmq.yaml

This is the config file of the gnB

I even tried modifying the amf file, as I thought that a version difference could be problematic, but it's giving the same error now for the amf

I am trying to implement slicing and for that I made changes in the config files of Open5Gs, where I updated the NSSF, AMF files and also changed the subscriber database.

According to the GPTs, initially it was the indentation, but later I was shown the result which stated about the config difference i.e. it requires an INI config (gnb.conf) and I need to do changes in that, but on checking I found that I don't have such a file.

The only config file which I have is named as gnb_zmq.yaml
It (AI model) also states that the yaml file doesn't support the function (s_nssai), which seems pretty strange
