Internal server error 500, hosting Node.js Express 4 application template from Visual Studio 2017 in Azure

I create a project from the project template: "Basic Azure Node.js Express 4 Application" in Visual Studio 2017 Enterprise edition.

enter image description here

When I run it locally it works fine. Now I publish this to Azure using the below Publish menu:

I get the following error:

iisnode encountered an error when processing the request.

HRESULT: 0x2
HTTP status: 500
HTTP subStatus: 1001
HTTP reason: Internal Server Error

I'm making no changes to the code from the template.

Any Ideas?

Solution

  • I followed your steps in Visual Studio 2017 Community edition. When I published the Express app to Azure Web App, I get the following error on my browser.

    The page cannot be displayed because an internal server error has occurred.

    After some investigation, I fixed it by changing the Web.config file to something like this:

    <?xml version="1.0" encoding="utf-8" ?>
<configuration>

  <system.webServer>
    <staticContent>
      <mimeMap fileExtension=".svg" mimeType="image/svg+xml" />
    </staticContent>
    <modules runAllManagedModulesForAllRequests="false" />

    <iisnode watchedFiles="web.config;*.js;routes\*.js;views\*.pug" />

    <handlers>
      <add name="iisnode" path="bin/www" verb="*" modules="iisnode" />
    </handlers>

    <rewrite>
      <rules>
        <rule name="NodeInspector" patternSyntax="ECMAScript" stopProcessing="true">
          <match url="^bin/www\/debug[\/]?" />
        </rule>
        <rule name="StaticContent">
          <action type="Rewrite" url="public{REQUEST_URI}" />
        </rule>
        <rule name="DynamicContent">
          <conditions>
            <add input="{REQUEST_FILENAME}" matchType="IsFile" negate="True" />
          </conditions>
          <action type="Rewrite" url="bin/www" />
        </rule>
      </rules>
    </rewrite>

    <security>
      <requestFiltering>
        <hiddenSegments>
          <remove segment="bin" />
        </hiddenSegments>
      </requestFiltering>
    </security>

  </system.webServer>

</configuration>

    Also, the web.config file can be found at https://github.com/projectkudu/kudu/wiki/Using-a-custom-web.config-for-Node-apps.

    Hope this will help you.
