Yeah, I'm pushing the friendship with things recently.
I was going through updating NR on some machines.
Alas one is being annoying - as usual.
I'm getting this error when it starts:
```auto

```
Sorry, but what's happened?
I can't resolve a _node_ that is causing the problem.
All I did was update a few nodes and import a working flow.

WHat did you actually do ?
Show us the NR startup logs so we can see versions etc
What platform and OS version is this running on ?

Hi @Trying_to_learn
you have hit an error in the internals of Node-RED. I cannot tell you what exactly it is or how it has been caused until I have time to step through the code and figure out what could cause this particular error.
Please let me know exactly what version of Node-RED you are running here.

(Though I see Nick is replying)
OS: Raspbian.

I had NR installed and working.
I went through and updated some of the nodes which were _old_ and very newer versions exist.
I also imported a small flow (generic) flow which I have on other machines.
This did mean I had to also install a couple of nodes which I didn't have installed - silly me.
(I try to have the same nodes on all machines to avoid this problem)
I deployed it and it just sat there.......
I SSH'ed into it and stopped NR.
I then restarted it and got that error.
Way above my skill set so I'll stop there and ask for help.

@Trying_to_learn can you send me your full flow file as a private message? (Click on my photo, then click Message).
I can see what will cause this error, but it should not be possible for a flow to get into this state. If I can examine your flow file it will help me understand it.

Here is the start log from the CLI:
```auto
pi@EyeSpyPi:~ $ cd .node-red
pi@EyeSpyPi:~/.node-red $ node-red-start
Start Node-RED
Once Node-RED has started, point a browser at http://192.168.0.89:1880
On Pi Node-RED works better with the Firefox or Chrome browser
Use node-red-stop to stop Node-RED
Use node-red-start to start Node-RED again
Use node-red-log to view the recent log output
Use sudo systemctl enable nodered.service to autostart Node-RED at every boot
Use sudo systemctl disable nodered.service to disable autostart on boot
To find more nodes and example flows - go to http://flows.nodered.org
Starting as a systemd service.

(Sorry not wanting to flood with multiple posts.)
Nick, here's a kicker (_rub?_):
The flow(s) were too big to send as one.
I tried to .zip them, but that isn't accepted.
I then was going to send you each (only 2) flow one at a time.
Node-Red had to be started in SAFE mode.
Alas while doing that I accidentaly added an unwanted node onto the screen.
Out of habit, I deleted the node and pressed the `deploy` button.
Now it works.
(There is another very underlying problem) of which I don't want to abuse the offer of help.)
I really REALLY appreciate you offered.
But now it is working.
Do you still want me to post the flow/s?

(ARGH! Got another problem on another machine.
Need to go off line and get that machine looked at with a real screen, etc.)

If it is now working then your flows won't help me understand what probably you were hitting.
But if its working then we can all move on.
