Hello everybody, I have a problem with loading an external function on a Raspberry PI. To load the module I added it in the "settings.js". functionGlobalContext: { arfunc:require('to-array') } In the function-node I include it. var arFunc = context.global.get('arfunc'); On my Win10 notebook it works fine, but on the rasp i get an error. 21 Oct 21:28:39 - [error] [function:DataToJSON] TypeError: Cannot read property 'toArray' of undefined I stopped and started node red several times, but it didn't solve it. :laughing: Any ideas, what I'm doing wrong? :thinking: Thanks in advance for any answer! Cheers KeMa

I'm answering my own last msg :grinning: :grinning: What I learned is this: when I hit Ctrl-C on the node-red console, it chops the console but it doesn't chop the node-red service, so I had been making edits, hitting Ctrl-C in the console and then kicking off the service again. That did not recycle the service and so did not pick up my changes. I learned that after the Ctrl-C, I need to run node-red-stop followed by node-red-start in order to deploy my changes. So, backing out stuff I didn't need... I didn't need to add an exports command to my dateformat.js I didn't need to have an index.js file in the dateformat folder - it had already been installed as a node using npm install and that was sufficient. All I needed was... functionGlobalContext: { dateformat:require("dateformat") }, in the settings.js and in my Function Node... var dateFormat = global.get("dateformat"); var theDate = new Date(msg.payload); var formattedDate = dateFormat(theDate, "ddd dd-mmm-yyyy"); msg.payload = formattedDate; return msg; then after properly restarting the service it all works. So, all along, the help given in this thread was spot on, and my problem was that the node-red service was not being recycled like I thought it was. Thanks for you help guys - I learned a lot.
