Hello there, i have a little problem like the title tells.  
I installed modules like xml2js & fast-csv on my host and want to use those functions inside a function node in nodered.  
So i added the modules to 'functionGlobalContext' inside settings.js (.node-red -\> settings.js)  
but then after restart i cannot connect to nodered in browser, it says err\_connection\_refused.  
btw, nodered is installed in a docker container..  
did i installed the modules the wrong way? what is the problem, i hope somebody can help.  
\*\*i installed the modules globally, but in the root directory..

best regards,  
Paul

Do you have access to the node-red log to see what error it is hitting?

Can you share exactly what you put in the settings.js file? You've probably accidentally introduced a syntax error in the file which prevents it from being loaded.

unfortunately, i cannot access the host system.. that means i cannot read the log right?  
I'm only getting access by ssh into the container and through [portainer.io](http://portainer.io) .

this is what i've edited in the settings file  
functionGlobalContext: {  
nodes7:require('nodes7')  
// fast-csv:require('fast-csv'),  
// xml2js:require('xml2js')  
...  
nodes7 is working in a function node but the others wont.

i also installed them right into the .node-red folder but nothing changed

The fast-csv and xml2js lines are commented out - remove the `//` at the start of them. You'll also need a comma, `,` to separate the nodes7 and fast-csv lines. Finally, you'll need to rename fast-csv as that is not a valid javascript identifier - use `fastCSV` (as an example).

```auto
functionGlobalContext: {
  nodes7:require('nodes7'),
  fastCSV:require('fast-csv'),
  xml2js:require('xml2js')
}

```

And make sure there is a comma separating this whole block from the settings above and below.
