I have set up the Roon Core node as per instructions and added the sample flow. I saw an extension appear in Roon, which I enabled.
Adding Debug nodes to the sample flow, I see data flowing, and I can see MQTT topics populating as well. So everything seems to be working.
However, after initial Node-Red startup, if I click 'Deploy', Node-Red will crash. My Node-Red (v2.1.4) runs in a docker, and if I inspect the log, I see that Roon Core is causing an error that seems to be the cause of the crash. If I restart Node-Red docker, all is well, until the next deploy.
Here's the relevant portion of the log file that shows the roon-core node crashing after the deploy command stops and restarts node and flows;
