Version 4 of Azure App Service Deploy - ERROR_USER

Question

This is a follow-up question to this question. The answer in the original question helped me, but I am stuck somewhere else. As a reminder, I want to deploy my application using a publish profile. My web app in Azure has two subfolders inside wwwroot and one of them is called backend. I want to deploy my application to that folder. I am not sure why msdeploy wants to create anything, since the web app is already there - I just need to get the artifacts inside the backend folder.

Here is the relevant part of the log (with some names changed to xyz):

Answer 1

I managed to resolve the issue. According to this answer by @starian chen-MSFT, I needed to set the correct parameter in SetParameters.xml. I did this by adding the following to my Visual Studio Build task:

/p:DeployIisAppPath="xyz"

where xyz is the value of DeployIisAppPath element in the publish profile.

Answer 2

The reason is that Azure expecting that site name will be presented twice in scm.azurewebsites.net:443/msdeploy.axd?site=%SiteNameHere%" and the same value as a parameter, by default value from file SetParameters.xml is used for second.

So, you need to modify the value of IIS Web Application Name parameter in xxx.SetParameters.xml programming (e.g. PowerShell or other tasks), after that it should works fine.
