(ErlangError) Erlang error: "Graphvix.Graph Graphvix.Graph received unexpected message in handle_info/2: :save_state\n"

Environment

• opus version: 0.5.3
• Elixir / Hex version (mix hex.info): 1.8
• Operating system: MacOS

Current behavior

When running my app I get the error above. My mix env:

{:opus, "~> 0.5.3"},
{:opus_graph, "~> 0.1", only: [:dev]},

[zorbash]

Hi @churcho this looks like an upstream bug of :graphvix. It should be harmless, since :opus_graph is meant to be started in dev env. However such an error raises suspicion to the developer, so I'll spend some time debugging this.
