Remote debugging: Error retrieving websocket debug proxy information from web.config

Using VS 2013 Ultimate Update 4, I'm getting the error

Error retrieving websocket debug proxy information from web.config

When trying to do Attach debugger (node.js) in the server explorer.

Did you try uncommenting and commenting out the relevant parts in the web.config file? Unless you're using web deploy, the web.config file does not undergo the debug transformation.

Not sure what you mean. This is my Web.config:

<configuration>
  <system.webServer>
    <handlers>
      <add name="iisnode" path="app.js" verb="*" modules="iisnode"/>
    </handlers>
    <rewrite>
      <rules>
        <rule name="DynamicContent">
          <match url="/*"/>
          <action type="Rewrite" url="app.js"/>
        </rule>
      </rules>
    </rewrite>
  </system.webServer>
  <!--
    For a description of web.config changes see http://go.microsoft.com/fwlink/?LinkId=235367.

    The following attributes can be set on the <httpRuntime> tag.
      <system.Web>
        <httpRuntime targetFramework="4.5" />
      </system.Web>
  -->
  <system.web>
    <compilation targetFramework="4.5"/>
    <pages controlRenderingCompatibilityVersion="3.5" clientIDMode="AutoID"/>
  </system.web>
</configuration>

We should add a better way of doing this, but you can either try creating one of the azure node templates, or look at the web config and web. debug.config in the following folder
https://github.com/Microsoft/nodejstools/tree/master/Nodejs/Product/Nodejs/ProjectTemplates/AzureExpressApp

Either try including the web.debug.config from there in your project and right click and select preview transform or something similar, and copy the result to your web.config file. Or start with the web.config in the template and uncomment/comment accordingly.

After you do that, you'll also need to enable web sockets from the azure website portal if you haven't already.

If you are using web deploy (which we don't recommend because you are more likely to run into #69) the debug transformation will happen automatically in the debug configuration so you wouldn't have to manually transform the file yourself.

Any updates on this issue? Did you manage to get it working?

I hit this issue also yesterday with the latest NTVS bits and a fresh Azure deployment. Looks like something is still amiss here.

I could attach using the 'Attach to Process' dialog rather than Server Explorer (as outlined at https://github.com/Microsoft/nodejstools/wiki/Advanced-Debugging#attaching-without-server-explorer ), so it would seem debugging was configured fine on the Azure end, it's likely the VS end which has the issue.
