Most likely you have some group writes coming from addresses that are not present on LM.
Replace get_value/knx_callback functions with this and see if it works:

Code:

function get_value(addr, datahex)
  local obj = dt_cache[addr]

  if obj == nil then
    obj = grp.find(addr)
    dt_cache[ addr ] = obj or false
  end
  
  if obj then
    return knxdatatype.decode(datahex, obj.datatype), obj
  end
end

function knx_callback(event)
  local addr = event.dst
  local value, obj = get_value(addr, event.datahex)

  if value ~= nil then
    send_metric('rawdata', obj.name, addr, value)
  end
end
