@thebaldgeek (Thebaldgeek) posted a new topic, subject "Flow stopped due to missing node types. npm". It read:

   Rebooted my Windows computer and was met with this when restarting.
    
    I have seen this error before with other nodes and you can usually install them and get running again, but this time I am stumped.... How can npm be missing?  
    What do I need to install to get running again?
    
    Doing `npm -v` shows 7.9.0  
    I think that means its installed, so how can it be missing?

    This is not referring to the `npm` command line tool.
    
    This means your flows have a node of type 'npm' in - and the runtime cannot find the module that provides that node type.
    
    Checking the flow library I see the module node-red-contrib-npm (node) - Node-RED provides that node.
    
    You could search your flows for `npm` to see where that node is (or possibly search for `unknown`). If it is a node you flows are actively using, then you'll need to install the `node-red-contrib-npm` module in the usual way, then restart Node-RED.
    
    If it isn't a node you are actively using, then delete it and hit deploy to restart your flows.

    Thanks so much for helping there Nick. The site was down and the avgeeks were getting cranky!
    
    I installed that node and we are back up and running. I just need to track down how/why that node is being used.  
    The error sure had me miss-directed.
    
    Thanks again for answering and helping out so quick.
