Solution

  • Those error messages are printed to the console. Please note that you need to supply the following command line arguments to your node in order to make this happen:

    1. --dev: Use the dev chain spec. You should already be using that.
    2. -lruntime=debug: Increase the log level for runtime generated messages.
