Error running candle to generate wixobj while building Windows in Github Actions

[nicolabeghin]

Following provided official reference https://github.com/gluonhq/hello-gluon-ci/blob/master/.github/workflows/windows.yml I set up Github Actions to package a JavaFX app at https://github.com/nicolabeghin/sap-commerce-cloud-management-api-gui/blob/native/.github/workflows/gradle.yml#L86

While Linux and MacOSX build successfully, the Windows one fails with

Error running candle to generate wixobj

I can see from
https://github.com/gluonhq/substrate/blob/master/src/main/java/com/gluonhq/substrate/util/windows/MSIBundler.java#L148 it's because Wix Compiler is not found, therefore I assume it's missing something in the Github Action example?

    if (candle.runProcess("Wix Compiler") != 0) {
        throw new IOException("Error running candle to generate wixobj");
    }

Whole stacktrace available at https://github.com/nicolabeghin/sap-commerce-cloud-management-api-gui/actions/runs/9382009047/job/25832508175

Also checked similar issue gluonhq/substrate#1085 by adding additional build.gradle properties but still no luck

thanks
