Hello,
I've some problems with a node that I've made. This node use request to do a simple get request to any server. When I used the node for first time, it run well. Now, I change de project to add new nodes and the first node doesn't work. When I try it, I recieve a notification that said: "Waiting for missing types to be registered: fiware-in" (fiware-in is the name of the node.
I try a lot of solutions, but anything runs.
Thanks!

Hi @trujillo - welcome.
That means Node-RED has not been able to load your custom module for some reason. It will have reported any errors it hit trying to load your node in the log - so that's the place to look first.

Before, I can see the modules in the command windows but now I can't. However, I can see the nodes in the palette and I can use it in the flow. When I deploy, the problems starts.

Show us the whole log, up to when the error occurs. If possible please copy/paste here from the terminal. You can use Ctrl+Shift+C to copy from the terminal.

This is my cmd when I deploy the node:

Given there are no errors at the start - around the 'Loading palette nodes' line - then the most simple explanation is it hasn't found a module that provides the type `fiware-in`.
If you take a look in the file `~/.node-red/.config.json` you'll see a list of all the modules node-red has loaded and where they came from. Check your module is listed in there.

The node is in the file that you comment. You can see fiware-out and fiware-in, the first runs well but the second has the problem and I don't know how repair it.
Thanks!

The runtime first identifies what types a node provides by scanning its html file - that is where the array of types comes from that you can see on line 502 in that screenshot.
It assumes the node's javascript file will actually register a node of that type.
But the error you are hitting tells us the javascript is _not_ calling `RED.nodes.registerType()` with a type of `"fiware-in"`. That would be the next thing for you to check.

This is the beginning of mi fiware-in.html. In the js file, RED.nodes.registerType() has 'fiware-in' too.
Thanks a lot for your comments!

You've shown the .html file - but its the .js file that determines what gets loaded in the runtime.

Ok, the js has an error.
Thank you very much! I solve my problem!
Thanks!

Hello,
I am facing exactly the same issue. I am learning how to create nodes, and having this same error. the difference is, as far as I can see, that I am declaring correctly the call to the neccessary type (in my case 'example') from `RED.nodes.registerType()`.
This is the log of node-red:
```auto

12 Apr 18:24:24 - [info] - example
```
This is the .js file:
```auto
module.export = function(RED) {
function ExampleNode(config) {
RED.nodes.createNode(this,config);
var node = this;
}
RED.nodes.registerType("example", ExampleNode);
this.on("input"), function(msg) {
if (typeof msg.payload === "string") {
msg.payload = msg.payload.toLowerCase();
node.send(msg);
} else {
node.error("Payload is not a String", msg);
}
}
}
```
The .html:
```auto
```
The package.json file:
```auto
{
"name": "node-red-contrib-example",
"version": "1.0.0",
"description": "",
"author": "",
"license": "ISC",
"node-red": {
"nodes": {
"example": "exampleNode.js"
}
}
}
```
It seems to be correctly loaded by node-red (fragment of : $HOME/.node-red/.config.json):
```auto
"node-red-contrib-example": {
"name": "node-red-contrib-example",
"version": "1.0.0",
"local": true,
"nodes": {
"example": {
"name": "example",
"types": [
"example"
],
"enabled": true,
"local": true,
"module": "node-red-contrib-example",
"file": "/home/maq/.node-red/node_modules/node-red-contrib-example/exampleNode.js"
}
}
}
},
```
Sorry I am sending a lot of data; just to show that I am considering all the possible mistakes commented here. After a number of hours trying different options, I haven't managed to put the node to work. I have to say that the node can be selected from the palette, but it cannot deploy the code as it says "Flows stopped due to missing node types."
Thanks a lot in advance

I have managed to see the problem; .js code was wrong. Two errors:
- Using module.export instead of module.exports
- Code inside exported function was not correc. This is teh correct version:
```auto
module.exports = function(RED) {
"use strict";
function ExampleNode(config) {
RED.nodes.createNode(this,config);
var node = this;
this.on("input"), function(msg) {
if (typeof msg.payload === "string") {
msg.payload = msg.payload.toLowerCase();
node.send(msg);
} else {
node.error("Payload is not a String", msg);
}
}
}
RED.nodes.registerType("example", ExampleNode);
};
```
What is difficult to me is to detect these kind of errors: java script is too permisive with data, so you can declare or use data out of scope, and nothing happens. Thanks
