My Node Red flow spontaneously stopped running due to the httrequest node disappearing! As it is a core node, I understand that a repair would necessitate re-installing Node Red. Since the Flow is on a Raspberry Pi 2b which may no longer be supported (or won't be soon), I am concerned that the default bash to re-install Node Red may not work. I also use Node Red on a raspberry pi Zero. The rpis are currently running Node.js v 20.19.1. So my query is it safe to use the current bash to re-install Node Red to "repair" the missing httpreqest node, and will there be a way to keep using Node Red on these devices when they require replacement microsd cards.

Hi,

no idea why a core node would disappear, any more info on what may have caused it, or the circumstances around that ?

Obviously make sure you back up your flows before you re-install or do anything drastic.

The latest script will work on a Pi2 and Pi0 - but will only install nodejs v22 as that is the latest/last version with armv6 processor support. You also need to be using at least PiOS bookworm or trixie (the latest) - it won't work on bullseye or buster.

In theory Node-RED requires nodejs v24 - but currently v5 still works on v22 so is ok at present - but over time some v24 (and later) features may creep in at which point it would stop working - but you can specify the Node-RED version on the install command line also so you should be able to keep them working - albeit without latest features (or security).

Did you mean that it won't work on bookworm?

OK so I bit the bullet and...  
Although the node red documentation says `if it detects Node.js is already installed, it will ensure it is at least v20. If nothing is found it will install the Node.js v22 LTS release using the NodeSource package.` The bash in fact tries to install v24, so had to add ` --node22` to the bash. Now running Node Red 5.0.7, and to my relief all my flows were still present and now functioning without even needing to import the backed-up flows. Which folders on the rpi should I back-up to ensure that I can still use Node Red on the rpi 2B when Node22 is not even an option. As to why the http request node disappeared while the program was running I have no idea.

Where are you seeing that? When I run the command I see

```auto
bash <(curl -sL https://github.com/node-red/linux-installers/releases/latest/download/install-update-nodered-deb)
 
Node-RED update script for : ...
 
This script checks if Node.js is installed, and will try to install
Node.js 24 if it is not found.

```

When Node 22 is no longer an option you will need either to backup the whole SD card so you can keep it alive as-is, ant try to upgrade, Or move to some other hardware, in which case you would need your user .node-red directory ( but not the node\_modules directory within it)

You are correct, the text there needs updating.
