Node-RED errors after update

General
1

I am running Node-RED in docker on Unraid. After an update, I can't get Node-RED to work right. The WebUI won't come up and I get some errors in the log file. I'm not sure what to do at this point.

Looks like you have an error in getting some global data. What did you update?
Try starting NR in safe mode node-red --safe and it should start letting you look at your code.

It updated last night after a power outage. I am running it in a docker image on Unraid and I am not sure how to get it to start in safe more. Can't find where I can add the option when it starts.

Found how to start in safe mode. Got it running that way now.

I was able to open the webui in safe mode. I disabled all flows and tried starting without safe mode only to get the same problem. Still getting the "warn" in safe mode.

You can see that the error report references the actionflows node. You will want to check that out first.

Then the error references RED.settings.functionGlobalContext which is defined in your settings.js file in your Node-RED data mount. Check there as well to see whether that is correct.

I removed some nodes that were not being used and that got rid of one error. I still have the Global Context one and can't figure that out. The error doesn't show in the logs when started in safe move, but does when started normally. All the flows are disabled though.

The only thing in settings.js I found about global context was the follow and it is the same as it was before the update...

    // The following property can be used to seed Global Context with predefined
    // values. This allows extra node modules to be made available with the
    // Function node.
    // For example,
    //    functionGlobalContext: { os:require('os') }
    // can be accessed in a function block as:
    //    global.get("os")
    functionGlobalContext: {
        // os:require('os'),
        // jfive:require("johnny-five"),
        // j5board:require("johnny-five").Board({repl:false})
    },

I think I fixed it. I updated the action flow nodes and the error has gone away.
