Http request throws error after nodejs update

General
1

Hey there,
I updated from nodejs 14 to 18 and re-installed node red.

Now, when I use the original example at
https://cookbook.nodered.org/http/simple-get-request
I get

[error] [http request:874a3d4e.9b666] RequestError: Expected value which is `predicate returns truthy for any value`, received values of types `Function`.

Any advice?

Note: the same http request works with node-red-contrib-http-custom-port-raw - but I'd rather want to use the standard module.

Hi @pebl-hank - welcome to The forums.

Can you confirm you're using the example as is, without modification? - i.e to get the latest Node RED version, if you are not, can please share an export of your flow?

I assume you are using the latest Node RED version?

The example work fine for me

I used the example code without modifications in a new flow.
Installed the latest version with

bash <(curl -sL https://raw.githubusercontent.com/node-red/linux-installers/master/deb/update-nodejs-and-nodered) --node18

Even with node20 it's same result.

Can you share your Node RED start up log?

Works fine on NR 3.1.0 and Node 16

could you try downgrading to Node16?

Anyone else running Node-RED 3.1 + Node18 - could you give the flow a try out please?

Ok entirely normal - just one of those things that needed to be asked :angel:

OK, I think I narrowed it down.
As soon as I install one of these pallettes, the described issue rises:

node-red-contrib-cul         <-- The one I am using currently
@johfer/node-red-contrib-cul
node-red-contrib-cul-max

I raised an issue here

but I'm not sure the package is still maintained. Is there anything I can do? I really need this pallette to be working.
