I'm using Symfony 6.4.4 with symfony/webpack-encore-bundle v2.1.1 and friendsofsymfony/jsrouting-bundle v3.5.0 The Typescript-Loader is also enabled.

i've actually started a fresh project with nothing special and i'm getting the following issue:

Running webpack ...

Executing pre-build scripts
Dumping exposed routes.

webpack compiled with 1 error

Process finished with exit code 1

the relevant webpack.config.js part looks currently like this:

...
.addPlugin(
        new WebpackShellPluginNext({
            //dev: true,
            onBuildStart: {
                scripts: [
                    'bin/console fos:js-routing:dump --format=json --target=public/js/fos_js_routes.json',
                ],
                blocking: true,
                parallel: false
            },
        }),
    )
    .addPlugin(new FosRouting())
...

But i can also remove both plugins and getting the same issue. The Export works as expected and the file is also generated.
