The eclipse-mosquitto:latestcontainer image that was referenced turns out to be v2.x, which no longer allows anonymous access (https://mosquitto.org/documentation/migrating-to-2-0/, see section 'Authentication requires configuration').
Since this is a POC focused on Protocol & Identity Translation, I figured a straight-forward solution would be to specify an older Mosquitto version instead (specifically, v1.6), to get things working again.
