How can I build and deploy a app (NestJS) as azure web app?

Question

I am use the nx framework (https://nx.dev) to create an angular + Nest application. The angular app should be the frontend application and the nest app should be the REST-API. I have create a git repo in "Azure DevOps".

I create this applications with

npx create-nx-workspace@latest
? Workspace name (e.g., org name)     nxtest
? What to create in the new workspace angular-nest      [a workspace with a full stack application (Angular + Nest)]
? Application name                    test-app
? Default stylesheet format           CSS

After this, i have an Angular and a Nest application.

I can start the angular frontend application with

nx serve test-app

and the Nest app (REST-API) with

ng serve api

It's worked an i can used the api at the browser.

In the next step, i commit and push it to the git repo.

I create in Microsoft Azure a Web-App.

Settings Microsoft Azure Web-App

Now, i want to create a CI/CD step.

In the azure portal ...

1. Choose Deployment Center
2. Choose Azure Repos
3. Choose Azure Pipelines
4. Choose my Organization, Project, Repo, Branch and as Web Application Framework NodeJS and Task Runner "None"

Settings for Deployment as Azure Web-App

After this, i have a new build pipeline in my "Azure DevOps" Project.

The create build pipeline run successful, but the build definition is somehow incomplete.

1. Use Node version
2. npm run install with the package.json
3. Archive files
4. Puplish build artifacts

The result on Azure:

• All files are copied from git repo
• create a web.config wit iisnode as handler and the path is "server.js"

But there are none start javascript file.

So, i edit the build pipeline.

Use Node version 12.13.0

Install application dependencies

Run Build The script "buildall" -> nx run-many --target=build --all --prod

When the run of the pipeline is finished, then i have this files in the wwwroot folder of the web app.

But if i run the app or visit the url, then i get allways the follow error in the console.

All my previous attempts to get the Nestjs application working have been in vain. I am grateful for any help.
