Electron platform support: The SAP NW RFC SDK could not be loaded

[siasty]

Hi, i have a specific problem with running the library. When I run a simple script with node-rfc everything works fine, but when I want to use the library in vs code extesion i have error "The SAP NW RFC SDK could not be loaded, check the installation " in first line "const noderfc = require("node-rfc");"

I also have settings in vs code to always includes libraries

do you have any idea what is wrong?

To Reproduce https://github.com/siasty/abaprfc.git command code hello world

Just found related SO question https://stackoverflow.com/questions/72011527/how-to-use-node-rfc-in-vscode-extension-development

Did you try to install the node-rfc globally, in nodejs version used by vs code?

[siasty]

yes I tried, i install nodejs version as usesd by vsc i also build node-rfc in my local machine but I have the same result

[bsrdjan]

in a first log (working example), the environment shows"nwrfcsdk_lib_on_path": true

in 2nd log (error), it shows "nwrfcsdk_lib_on_path": false which means SAP NWRFC SDK dll files are probably not on path.

The RFC SDK dll files path is determined by SAPNWRFC_HOME env variable and lib subfolder added, should be c:\nwrfcsdk\lib on your system.

Can you check if c:\nwrfcsdk\lib is on PATH when running from VSCode? Print the PATH to console before (or without) loading node-rfc for example.

[siasty]

Hi, environmental values are set correctly and read by vscode.... I've tried many things ;/ maybe that's why I had "nwrfcsdk_lib_on_path": false .... from log...

and code of simple extension `import * as vscode from 'vscode';

export function activate(context: vscode.ExtensionContext) {

console.log('SAPNWRFC_HOME: ' + process.env.SAPNWRFC_HOME);
console.log('Path: ' + process.env.PATH);

let disposable = vscode.commands.registerCommand('testrfc.helloWorld', () => {

    vscode.window.showInformationMessage('Hello World from testrfc!');
});

context.subscriptions.push(disposable);

}

export function deactivate() { } `

Hi, I think I have the same problem, but outside of vscode. I configured everything correctly and it still gives me the same error. I did a test calling the SDK through python and the connection worked correctly

[siasty]

Hi i also use pyrfc to test and works correctly

[Zefau]

Any solution / ideas on this? I'm experiencing the same issue.

[bsrdjan]

@siasty could you please describe step by step how to reproduce? From cloning the extension repo to getting the error line in screenshot?

[bsrdjan]

I could not reproduce on MacOS, see screenshot below. Is it how it is supposed to work?

[siasty]

hello I have to write a new repository this source has evolved to something else I didn't have the strength for node-rfc anymore. i start using pyrfc

[siasty]

in the evening I will add a new source

[siasty]

[bsrdjan]

Finally reproduced on Windows only, it works on MacOS and Linux.

SAP NWRFC SDK is not supported on electron platform, on which VS Code is running and that is why it is not loading on Windows. The feature can be requested from SAP product development, as described here: https://github.com/SAP/node-rfc/issues/144

The test is done by standard generated "Hello World" extension, with following trace added to extenstion.ts:

      // Display a message box to the user
      const RFC = require("node-rfc");
      const client = new RFC.Client({
        ashost: "host",
        user: "user",
        passwd: "passwd",
        sysnr: "00",
        lang: "en",
      });
      vscode.window.showInformationMessage(JSON.stringify(client.environment));

[bsrdjan]

Electron is supported as of node-rfc@3.1, also on Windows
