Javascriptservices（带有Node.js的ASP.NET核心）在部署到IIS后无法正常运行

很抱歉，如果缺少任何信息。

我正在使用节点模块API将图形导出到在IIS中无法使用的png。

为了进行测试，我尝试使用opn nodejs API打开png图像。在本地Visual Studio 2017 IIS Express中运行良好。但是在发布到IIS后无法正常工作。

我收到以下错误消息。

cs代码 

   public async Task<string> TestNodeMules()
    {
        // setup the services
        var services = new ServiceCollection();
        services.AddNodeServices(options =>
        {
            options.ProjectPath = Directory.GetCurrentDirectory();
            // Set any properties that you want on 'options' here
        });

        var serviceProvider = services.BuildServiceProvider();
        var nodeServices = serviceProvider.GetRequiredService<INodeServices>();



        var result = await nodeServices.InvokeAsync<string>("./GraphPlottingServerSideJS2/app.js");



        return result;

    }

JavaScript Nodejs代码 

const opn = require('opn');




module.exports = function(callback){

  // Opens the image in the default image viewer
opn('graph2.png').then(() => {
  // image viewer closed
  callback(null,"success");
})
.catch(err => {
  callback(null,"success"); 
  });

}
