Hello,

after presentation available here I thought that I can run JavaScriptService for example to saving somekind images via node - or receiver stream in ASP.NET Core app and then save it. But then I implemented it and it does not work :(

so i created very simple nodejs function:

var im = require('imagemagick');

var fs = require('fs');

module.exports = function (callback, pathToImg, destinationPath) {

     im.resize({
        srcPath: pathToImg,
        dstPath: destinationPath + "test.png",
        width: 256
    }, function (err, stdout, stderr) {
        if (err)
        { callback(error, "error"); }
        callback(stdout, "success");


    });
    
};

And Im trying to invoke this code via ASP.NET Core JavaScriptService :

var result = await _nodeService.InvokeAsync<Stream>(@"Node\test.js", file.Path, $"{new FileInfo(file.Path).Directory.FullName}\\testtest.png");

and i get error:

HttpRequestException: An error occurred while sending the request.
System.Runtime.ExceptionServices.ExceptionDispatchInfo.Throw()

Am I doing here something wrong?
I have problem with debugging node.js code via node-inspector. I cannot inspect my code.

Here is stacktrace:
