Bluetooth tether not working

I have the following script bellow. I have paired my laptop and phone. However I cant ping over the connection. I get a Host destination unreachable error....
Everything else looks like its correct. How can I debug where the issue is?

function fn_bluetooth_tether {

    yay --noconfirm --needed -S nftables
    yay --noconfirm --needed -S bluez bluez-utils

    bluetoothctl devices
    # awk, find line 'Device' and get 2nd entry on line
    # sed replace : with _
    device_mac=$(bluetoothctl info | awk '/^Device/{print $2}' | sed 's/:/_/g')
    dbus-send --system --type=method_call --dest=org.bluez /org/bluez/hci0/dev_${device_mac} org.bluez.Network1.Connect string:'nap'
   
    # bnep0

    sudo nft add chain ip nat postrouting { type nat hook postrouting priority 100 \; }

    # add rule
    sudo nft add rule nat postrouting oifname ${inet} masquerade
}
