Node-Red will not complete loading with projects enabled

General
1

Node-Red is Installed with all defaults.
Normal operation until "projects" is enabled.
Then when starting I get:
Graph showing "Loading Nodes 1/59 that stops at 59/59"
Error: Failed to load ‘node-red/comment’
Normal operation resumes after disabling "projects" and restarting node-red.

Node-RED version: v1.2.7
Node.js version: v14.15.3
Dashboard version 2.26.1 started at /ui
Windows_NT 10.0.18363 x64 LE
Win10 pro v1909 6700K w/ 32 GB Ram
Firefox, Chrome and Edge give identical results.
Have uninstalled and reinstalled node-red using Power Shell w/ Admin - forced all new default directories

With a new node-red install and projects enabled:

Thanks for any trouble-shooting suggestions as I am very new to this!

If you have not already done so then clear the browser cache, do a full page refresh in the browser and see if that fixes it.
If not then what browser are you using? Are you able to try another browser (not IE)?
If still not then have a look in the browser developer console to see if there are any errors there.

Hi Colin:
Thanks for the help.
I restarted windows and then cleared FireFox as you suggested but got the same failure.

After clearing the previous errors from the Browser Console and re-starting Node-Red it shows:
Content Security Policy: Ignoring “'unsafe-inline'” within script-src: ‘strict-dynamic’ specified
Content Security Policy: Ignoring “https:” within script-src: ‘strict-dynamic’ specified
Content Security Policy: Ignoring “http:” within script-src: ‘strict-dynamic’ specified

This sequence continues to repeat.

Have you tried a different browser?

5

Yes, Chrome and Edge and IE.

6

You say it is loaded with all the defaults, but I see you have got a flow running. Did it work previously? If so then start node-red using
node-red --safe
which will start without running the flows. If that is ok then undo whatever was the last thing you did and deploy.
Alternatively restore the flows file from your most recent backup.

7

Using node-red --safe had the same results. I even restarted windows.

The problem is with projects enabled - OK when disabled.

Projects had worked before but not initially. I could start the flow with projects disabled, then enable it in settings.js and restart node-red. The flow would then reconnect with projects enabled. The project feature would work for days until I would, say import a new module such as random.

Yesterday, an import again disabled projects. I removed node-red and reinstalled it. While the Flows are now much faster and the snap to grid feature now functions, I can no longer get projects to work even as before.

8

Rename the .node-red folder so you start with a clean sheet. Then try again and make sure it starts up ok. Then enable projects in settings.js and restart node red.

I suspect that it is one of the installed nodes (which are in .node-red/node_modules) that is causing the problem.

Edit: are you using the Victron nodes?

9

... err how can that happen ? projects is enabled in your settings file... any normal import can't touch that. Not sure what you are importing but that doesn't sound right to me.

10

I have already tried to rename .node-red. It gave the same results.

11

When I was able to have projects working and imported a new node, sometimes the flow UI would no longer load. As soon as I would disable projects in the settings.js file, The flow UI would again load. Then enabling projects in the settings.js file again causes the flow UI to hang.

12

Not possible, since the flows file that the log references would not exist.

Edit. Can I just check that you have verified that if you stop node-red that the browser times out trying to load the editor.

13

The browser tab stays active with a drop down box message "Lost connection to server, reconnecting..."

14

OK, just wanted to check that there wasn't another node-red running somewhere. So post the log after renaming .node-red please.

15

I have projects enabled now. Disabled node-red-contrib-multiproject and the dashboard nodes in the process. However after enabling the dashboard nodes, I get the error:

The workspace contains some nodes that are not properly configured:

  • [Flow 2] button (ui_button)
    Sigh!
17

Use Search to find the button and correct whatever it doesn't like.

18

Well, that would be my very first port of call if I were having problems like this. It hasn't been updated in over 4 years and the chances of it behaving well are pretty low.

Get rid of that first before trying anything else.

19

Thanks - done.

Now working to get all the dashboard functions to work. Have 10 working but ui form, numeric, slider and template cause error when Deployed. Error:

The workspace contains some nodes that are not properly configured:

  • [Flow 1] button (ui_button)
  • [Flow 1] slider (ui_slider)
20

Are they displayed in the flow with a red triangle? What do you see if you open one of them. Make a small change and see if that fixes it.

Colin:
Thanks for all your help in getting me to a stable node-red installation.

All the nodes seem to work as expected now. And Projects are working too.

Now if you could just transfer some of your insights and experience...

Thanks,
Larry
