This helped me. Hope it helps you.

Add this to your web.config in the root of your project

<configuration>
  <system.webServer>

    <!-- indicates that the server.js file is a node.js application 
    to be handled by the iisnode module -->
    <handlers>
      <add name="iisnode" path="server.js" verb="*" modules="iisnode" />
    </handlers>

    <!-- adds server.js to the default document list to allow 
    URLs that only specify the application root location, 
    e.g. http://mysite.azurewebsites.net/ -->
    <defaultDocument enabled="true">
      <files>
        <add value="server.js" />
      </files>
    </defaultDocument>

    <!-- Ensure all errors are sent to the node.js application for better error handling -->
    <httpErrors existingResponse="PassThrough" />

    <!-- Ensure the Node.js application can handle all URLs -->
    <rewrite>
      <rules>
        <rule name="NodeJS" stopProcessing="true">
          <match url="/*" />
          <action type="Rewrite" url="server.js" />
        </rule>
      </rules>
    </rewrite>

  </system.webServer>
</configuration>

create a server.js file and add the code below

const { createServer } = require("http");
const { parse } = require("url");
const next = require("next");

const dev = process.env.NODE_ENV !== "production";
const app = next({ dev });
const handle = app.getRequestHandler();

app.prepare().then(() => {
  createServer((req, res) => {
    const parsedUrl = parse(req.url, true);
    handle(req, res, parsedUrl);
  }).listen(process.env.PORT || 3000, (err) => {
    if (err) throw err;
    console.log("> Ready on http://localhost:3000");
  });
});

finally in your package.json, edit your start script

 "start": "node server.js"

I am using AzureResourceManagerTemplateDeployment@3 task to deploy an azure ad b2c tenant using the release pipeline.
When I was manually running the script using my local PowerShell then it was running smoothly but in release pipeline, I got the same error as yours:

Now the thing is that I tried giving every related admin rights like subscription owner and ad b2c global administrator. I wasn't able to resolve the issue. Could you please help me with this?
