unknown: mosca in in Node-RED on IBM Cloud

Question

I followed the instructions on http://www.steves-internet-guide.com/install-mosca-mqtt-broker-node-red/ on IBM Cloud.

I installed the node-red-contrib-mqtt-broker, but got the error "unknown: mosca in".

Installation error in app log:

Answer 1

OK, so as the log states, Node-RED has been unable to install the node.

Your best bet is to edit the package.json for the app so it is installed during app staging then restage the app. The easiest way to do this is to enable continuous integration for your app. I've not used IBM-Cloud in a while, so you'll have to check the docs for how to do this.

It's probably also worth noting that you will not be able to access the MQTT broker from outside Node-RED when running the mosca node on IBM-Cloud. This is because the IBM-Cloud environment only exposes one port from any application. In Node-RED's case this is the HTTP port.
