I am working on migrating a web application to Next.js in this repo. However, I am running into an issue where the basePath is seemingly not injected.

My configuration looks like the following:

const withPWA = require("next-pwa")({
	dest: "public",
});

module.exports = withPWA({
	compiler: {
		styledComponents: true,
	},
	reactStrictMode: true,
});

However, the step using the actions/configure-pages action outputs this warning from #43:

Warning: Unsupported configuration file extension. Currently supported extensions: ".js", ".cjs", ".mjs"

Other than the fact that the next.config.js configuration uses the .js extension, it seems that the action fails to inject properties into a configuration wrapped by a higher-order withPWA function. A more useful error is not logged, so this issue is hard to diagnose.
