Could you please describe steps / commands, how to reproduce?

from node-rfc.

I can try yes

I have installed node.js in the LTS version with all additional addins.

then I tried to install the RFC Node, which unfortunately failed.

From then on it became uncontrolled and I can no longer say exactly what I tried

from node-rfc.

then I tried to install the RFC Node, which unfortunately failed.

which installation method?

Did you check SAP NWRFC SDK installation as described here?
https://github.com/SAP/node-rfc/blob/main/doc/installation.md

from node-rfc.

Ah, I don't have the SAP NWRFC SDK yet. Unfortunately, you can only download it with a login.

That's why I've now asked my customer if he can make it available to me.

from node-rfc.

It should work then. SAP NWRFC SDK is platform specific, therefore check if version for Windows is downloaded.
Also check if required VS C++ redistributable is installed: https://github.com/SAP/node-rfc?tab=readme-ov-file#windows

from node-rfc.

We are one step further and the installation worked with the SDK.

Now I have set all paths according to the instructions. However, when starting Node-Red, the error appears on the print screen

from node-rfc.

node-red platform is not supported, see #148

from node-rfc.

I have now changed the Node-Red version, the error remains the same:

But I also see that my node-rfc folder is missing:

from node-rfc.

As per following steps, I could not reproduce the same error on arm64 Mac

install and start node-red

mkdir test
cd test
npm i node-red
node-red

install node-red-contrib-saprfc via Menu > Manage Palette

configure sapRFC call node

system

bapi call

error after flow started

After flow (re)started, following error is reported

11 Jan 15:43:40 - [info] Stopping flows
11 Jan 15:43:40 - [info] Stopped flows
11 Jan 15:43:40 - [info] Starting flows
11 Jan 15:43:40 - [error] [saprfc-config:2fce0260e94f4686] Error: Pool configuration object must provide "connectionParameters"

The node-rfc is installed and loaded and error is thrown from node-rfc C++ wrapper because connectionParameters are not passed correctly.

It looks like bug in node-red-contrib-saprfc and @PaulWieland might eventually help, or you can create the issue in https://github.com/PaulWieland/node-red-contrib-saprfc

node-red integration is not in scope of this project support

from node-rfc.

What is the extension of your files in the bin folder of the SDK? .exe or .ex_?

from node-rfc.

It is exe, as in original NW RFC SDK package for Windows, on SAP Service Portal.
The download link is in https://me.sap.com/notes/2573790

from node-rfc.

thx

from node-rfc.

I have now had no more errors when installing node-rfc. However, I still get the same error when starting node.red:

Your flow credentials file is encrypted using a system-generated key.

If the system-generated key is lost for any reason, your credentials
file will not be recoverable, you will have to delete it and re-enter
your credentials.

You should set your own key using the 'credentialSecret' option in
your settings file. Node-RED will then re-encrypt your credentials
file using your chosen key the next time you deploy a change.

The installation worked. The following update was still missing for the SDK to work properly:
