The network monitor crashes if the chain of the nodes being monitored has not started. This can be fixed by checking for the presence of the "last_block_height" value before trying to obtain it, or using the "last_block_height" value under NODE:26657/status/, which seems to be available even before the chain starts.
The error message is:
Network monitor (NETWORK_MONITOR_NAME) terminated due to exception: 'last_block_height'
