The Industrial Raspberry Pi Forum

When trying to launch Node red through the revpi status screen I get the following message 'Node-RED service not ready yet ... please retry ...' The star icon appears green, but every time you click on it the same error appears.

We have already tried to remove the "Group=pi" line and reboot but the result is the same.

if I try to access through the terminal (node-red -v), it does access me.

someone can help me, I have been unable to access for several days.

Thanks

There seems to be something which breaks your NodeRed. Try with an empty flow and disable unnecessary nodes. This error can also occur if you use nodes which require a more recent nodejs version.

Hi Nicolai,

Thank you very much for your answer

How can I deactivate the nodes through terminal?
Is there any way to copy all the flows through terminal and delete them to add them again one by one?

Kind regards

Can you try to access Node-RED directly?

Node-RED should run on https://revpiXXXXX.local:41880/. It's exactly the same URL as RevPi status, but on port 41880. It could be that the dialog in RevPi status has an error and Node-RED is actually running.

Hi,

I enter the ip address of the rev pi followed by :41880 and it gives error, i have also tried with:1880 which was the one i used to enter before and it also gives error.

Would it be possible for you to flash the RevPi with our Bookworm image?

Node-RED is already installed in the default image, including the GUI. If you do not need the GUI, you can use the Lite image and install Node-RED in the cockpit (web configuration). The version of Node-RED is there v4 and is regularly updated via package updates.

we always work with the graphical interface, in fact I don't know how we can delete nodes and flows without accessing the graphical interface.
