Helix Publishing Pipeline Error - "No element in the source document matches configuration/appsettings/add'

Question

Using Sitecore 9.2, SXA, and Helix Publishing Pipeline (HPP).

As per the HPP documentation (https://github.com/richardszalay/helix-publishing-pipeline), we are using Web.Helix.config files to transform the web.config.

When building, I'm getting the error No element in the source document matches configuration/appsettings/add in the file \obj\Debug\HelixTransformWebConfig

I've compared our implementation to the HPP example client, and HelixBase and can't any differences. In fact, that generated HelixTransformWebConfig is structured the same

<configuration>
  <appsettings>
    <add key="Feature2.ConfigKey" value="Feature1.ConfigValue" xdt:Transform="Insert" xmlns:xdt="http://schemas.microsoft.com/XML-Document-Transform" />
  </appsettings>

Ideas?

We aren't using a namespace other than "http://schemas.microsoft.com/XML-Document-Transform" on the web.config anywhere, and our Website.wpp.targets is as requested by the documentation

Answer 1

This is not a problem with Helix Publishing Pipeline. The error indicates an issue with the section being transformed.

Can you try the below transform for your appsettings.

<appSettings>
    <add key="Feature2.ConfigKey" value="Feature1.ConfigValue" xdt:Locator="Match(key)" xdt:Transform="SetAttributes" />
