Hi , just received my RevPi Connect 4
OS : Linux RevPi109168 5.10.152-rt75-v8 #1 SMP PREEMPT_RT Tue, 26 Sep 2023 09:43:32 +0200 aarch64 GNU/Linux
Successfully install the nodered
When trying to start node red, keeps getting error:

Hi dear esktan, that sounds like a bit of a mixed bag and there are certainly different ways that can lead to dead ends when installing Node-RED and the extensions on the Revolution-Pi module. What I can recommend to you is the following checklist https://kunbus-gmbh.atlassian.net/servi ... 2632253480
There we have summarized all the steps that lead to success and navigate you safely through this installation jungle.

Hi Dirk,

Thanks for the response.
I have try to uninstall the node-red and re-install but still the same error.
Was a bit surprised that Node-red does not come in this new RevPI Connect 4.

sudo npm -g remove node-red
sudo npm -g remove node-red-admin
rm -R ~/.node-red

bash <(curl -sL https://raw.githubusercontent.com/node- ... nd-nodered)

This is another article I found but I'm not sure what is the resolutions.

Is there any other suggestion you can share?
Please advise
Thanks

Hi esktan, I'll create a test setup and clarify if Node-RED is included in 2023-09-26-revpi-bullseye-arm64.img.

Hi esktan, I have tested Node-RED, and it works out of the box with RevPi Bullseye 64-bit (09/2023) (ID: 7482).
Here is my step-by-step guide:

: Activate Node-RED Service

: Start Node-RED App

: Finally Node-RED!

Hi Dirk,

Thanks for your test.
I have followed your suggestion, and below is the screenshot for your understanding.

Will try to perform to reload the image you describe for further testing.

Hi, esktan Why do you take the last step and not just wait until Node-RED has started? I have to admit, I also got this dialog shortly after I did the first step. However, since it worked immediately after waiting less than a minute and reloading the page, I didn't think it was relevant to document - but I'll do a bit better in the future and comment on that too.

Hi Dirk,

Thanks for the information. I have passed the unit to my colleague to try going through your suggestion again, as I am a newbie in RevPi.
So, hopefully it is just something simple that I missed. We will keep you posted if we get it working.

Thanks
