Editor stuck at "Adding Flows to workspace"

After upgrade to 1.2, the editor stops at "Adding Flows to workspace". It appears to be the same issue experienced here:



I'm afraid I cannot follow the debugging steps used before. Is there an easier way to find and remove the offending node? If that is the likely problem?

Hi @taisau

How do you run Node-RED?

If you can set the NODE_ENV environment variable to development before running Node-RED, then you'll get the non-minified version of the editor code - so the stack traces will be easier to follow.

Thanks, @knolleary.
Running on a raspberry pi, installed with the script.
It would appear that it is brads-i2c-nodes causing it.
I'll try reinstalling or rebuilding the node.

I am getting the same problem with a variation in that if I uninstall and reinstall Node-RED.

It works for about six hours and then starts exhibiting the problem.

After installing Node-RED I use the pallet manger to also install:

node-red-dashboard
node-red-contrib-ds18b20-sensor
node-red-contrib-unit-converter
node-red-contrib-alexa-remote2
@victronenergy/node-red-contrib-victron

I had done an export with all flows as a backup.

Which I used to recover from after reinstalling NodeRED. There is some hidden error in that process.

It seems to be stable after:

  1. Importing all flows.
  2. Export the individual flows separately.
  3. Delete all flows and configurations
  4. reimport each flow individually

I never really pinpointed my problem, just solved it by std procedure of removing and changing random things. I also had the Victron nodes installed, and I recall a msg stating something like they did not have valid node id's. My impression was that the 1.22 update identified and isolated those invalid nodes, where the 1.20 did not.

I spoke too soon the problem has reappeared. The last thing I remember doing last night was adding the Victron library and coding up some web GUI.

I have an older NodeRED installation that is running the Victron library, will have the required functionality output to MQTT and then under 1.2.2 consume for the web GUI.

Definitely somewhere in the Victron nodes!!! I did the following commands and it loaded the flows with a warning about the missing nodes.

  • sudo systemctl stop nodered
  • cd ~/.node-red
  • npm remove @victronenergy/node-red-contrib-victron
  • sudo systemctl start nodered

Here's flow that I believe causes the error:

What exactly is the problem that you are having? If you uninstalled the victron node and still have the nodes in the flow then when you start node-red it will hang saying there are missing nodes.

No it warns you of the missing Victron nodes and then takes you into the full editor environment where you can make then changes. If push comes to shove I could load the Victron nodes again and the functionality would be restored. However that would return to the original problem of locking you out of the editing environment.

In my case I have chosen to run the Victron nodes on a Raspberry Pi that I haven't updated yet and pass data to and from via MQTT.

Actually I have notice a big improvement in responsiveness by having two RPI's. One handling logic and the other handling the web GUI with MQTT as the interface between the two.

Well this is very odd, I am seeing something similar. Even after removing the victron nodes and all references (including checking for configuration nodes) when I restart node-red it hangs when loading the editor. When I look in my flows file I see

    {
        "id": "victron-client-id",
        "type": "victron-client"
    },

If I delete that bit of the file (make a backup first and then make sure you delete it including the comma on the end, then restart node-red all is well. But a bit later after some more deploys that section has come back again. So the short term workaround is to delete that, but I haven't worked out why it keeps coming back.

What version of node-red are you running? You can see it at the bottom of the hamburger menu dropdown.

I see what I had done, I had not properly uninstalled the victron nodes. That is why it kept coming back.
There is definitely an issue with the victron node causing it to hang on reloading the editor, but if you uninstall the victron node and restart node red and refresh the browser then it tells you there are missing nodes and you can remove them.
So I think you will just have to wait for a response from the node author.
