6 years ago Looks like a problem with your flow. Can you share the flow json file? (notice that it might contain passwords and secret credentials - delete them before sending). I assume that the uri string of the mongodb2 configuration-node is somehow undefined.

6 years ago my problem is not in the flow itself(as i didnt put my flow yet in node-red), the problem is i cant see the node itself in the node list on the left side of the screen for example when i run node-red using the 'sudo node-red' command
but if i run node-red using supervisor 'sudo supervisorctl start NodeRed':
and when i cat the log file it`s shown like :

6 years ago the other libraries is okay , i did quick debugging and actually it`s not only the nanopi but also on my desktop as well ,i go through node-red code and the problem start from here :
`try {
var loadPromise = null;
var r = require(node.file);
if (typeof r === "function") {
var red = createNodeApi(node);
var promise = r(red);
if (promise != null && typeof promise.then === "function") {
loadPromise = promise.then(function() {
node.enabled = true;
node.loaded = true;
return node;
}).otherwise(function(err) {
node.err = err;
return node;
});
}
}
if (loadPromise == null) {
node.enabled = true;
node.loaded = true;
loadPromise = when.resolve(node);
}
return loadPromise;
} catch(err) {
node.err = err;
var stack = err.stack;
var message;
if (stack) {
var i = stack.indexOf(node.file);
if (i > -1) {
var excerpt = stack.substring(i+node.file.length+1,i+node.file.length+20);
var m = /^(\d+):(\d+)/.exec(excerpt);
if (m) {
node.err = err+" (line:"+m[1]+")";
}
}
}`in node-red/red/runtime/nodes/registry/loader.js
i am still debugging the problem to see why node-red can't load the node when it's used with supervisor

6 years ago i already solved the problem , actually it`s the configuration file in /etc/supervisor/conf.d/ , the way i set it cause the problem the correct working configuration can be find here :

6 years ago OK, happy for you for solving the problem :smile: , I'm closing the issue.
hello
i have been running node-red and use the mongodb2 node for while on nano pi neo air but when i run node-red with supervisor the node disappear and this the output of the log
but if i run the node-red normally it appear again and no problem at all
i tried to re install node-red and reinstall mongodb2 node sudo since supervisor run in root mode but no luck
the node-js version i have test it on is : latest 6.12.0 6.9.2
the os used on the nanopi neo air is the officel : Distribution: Ubuntu 16.04.3 LTS Kernel version: Linux 3.4.39-h3 armv7l
