The config files have been updated in the latest release, this error indicates that there is an unsupported or wrongly defined parameter being configured.

It looks like you are using the latest release, in this we updated the CU-UP configuration fields. The nru field is now no longer used. Instead, the CU-UP configuration options look like this:

cu_up: 
  gtpu_queue_size: 2048                # Optional INT (2048). Sets the GTP-U queue size, in PDUs.
  gtpu_reordering_timer: 0             # Optional INT (0). Sets the GTP-U RX reordering timer (in milliseconds).
  warn_on_drop: false                  # Optional BOOLEAN (false). Enables the option to log a warning for dropped packets in GTP-U and PDCP due to full queues. Supported: [false, true].

  f1u:
      socket:                               # Define UDP/IP socket(s) for F1-U interface.
        -                                     # Socket 1
          bind_addr: 127.0.3.1                  # Required TEXT. Sets the address that the F1-U socket will bind to.
          ext_addr: 8.8.8.8                     # Optional TEXT. Sets the address that is reported as the F1-U bind address. If empty, the real bind address is used.
          udp:
            max_rx_msgs: 256                        # Optional UINT (256). Sets the maximum packets read from the socket in a single syscall.
            pool_threshold: 0.9                     # Optional FLOAT (0.9). Sets the pool occupancy threshold, after which packets are dropped. Supported [0 - 1.0]. 

  ngu: 
    no_core: false                        # Optional BOOLEAN (false). Setting to true allows the gNB to run without a core. Supported: [0, 1].
    socket:                               # Define socket(s) for NG-U interface.
      -                                     # Socket 1 
        bind_addr: 127.0.3.1                  # Optional TEXT (auto). Sets local IP address to bind for N3 interface. Format: IPV4 or IPV6 IP address.
        udp:
          max_rx_msgs: 256                      # Optional INT (256). Sets the maximum number of messages RX from a socket in a single syscall.
          pool_threshold: 0.9                   # Optional FLOAT (0.9). Sets the pool occupancy threshold, after which packets are dropped. Supported: [0.0 - 1.0].
          dscp:                                 # Optional UINT. Sets the Differentiated Services Code Point. Supported: [0 - 63].
