Troubleshooting ReadFiles not finding any files

[girlpunk]

I'm trying to get Statiq to run Webpack, to allow for tailwind CSS classes to be generated. Webpack itself is working, and creating the CSS and JS files as expected, however trying to add these as documents for output with ReadFiles is not working.

My pipeline to achieve this looks like this:

bootstrapper.BuildPipeline(
    "Webpack",
    builder =>
        builder
            .WithProcessModules(
                // Run webpack
                new StartProcess("npx")
                    .WithArgument("webpack")
                    .WithWorkingDirectory(nodeDirectory)
                    .KeepContent()
                    .LogErrors()
                    .LogOutput(),

                // Collect the files from Webpack
                new ReadFiles(Path.Combine(nodeDirectory, "dist", "*")),

                // Set the output destination for the files to the assets folder
                new SetDestination(
                    Config.FromDocument(
                        (doc) =>
                            doc.Source.Extension == ".css"
                                ? new NormalizedPath("assets/css/styles.css")
                                : new NormalizedPath(
                                    "assets/"
                                        + doc.Source.Extension.Replace(".", "", StringComparison.InvariantCultureIgnoreCase)
                                        + "/"
                                        + doc.Source.FileName
                                )
                    ),
                    true
                ),

                // Write the files to the output
                new WriteFiles()
            )
            // run before content analysis
            .AsDependencyOf("AnalyzeContent")
            .AsDeployment()
            // Run after other phases that would create content with CSS classes in
            .WithDependencies(
                "Archives",
                "Assets",
                "Content"
            )
);

The initial step of running Webpack works and the files are generated in webpack's dist folder, however Statiq's logs indicate that ReadFiles does not find any files in the folder. Using specific filenames instead of the globbing pattern gives the same result. Adding a LogMessage before the ReadFiles indicates that the path searched for the files is correct.
