Azure DevOps Pipeline issue - azure-devops

Question

I am struggling to get a simple build and deploy working and was hoping for some assistance. Could anyone review the steps and also why the Publish Artifacts does not work? It's a simple Angular 7 project.
Error:

Azure DevOps Pipeline issue
The Publish Build Artifacts task is used to publish build artifacts to Azure Pipelines, TFS, or a file share.
But, just like Daniel and Andrey said, although you add the npm build, you did not set the installed folder to be dist. So the result of npm build will not be saved in the dist folder. In this case, the folder dist is empty.
Besides, to save the build result to the dist folder, you can try to use the option -- -op like following:
run ng build --prod -- -op ..\..\dist
The ..\..\dist should use relative path based on the project.json file.
Check the document JavaScript frameworks: AngularJS for some more details info.
Hope this helps.
