svg-sprite-loader: Error: "request.includes is not a function"

I’m getting the following error when attempting to use this plugin:

C:\Root\Apps\@V\DebateMap\Main\node_modules\svg-sprite-loader\lib\utils.js:168
if (request && (!request.includes(spriteLoaderPath) || !rule)) {
                           ^

[nodemon] app crashed - waiting for file changes before starting...

Here is my config: (well, the relevant part, as it is quite large)

const SpriteLoaderPlugin = require("svg-sprite-loader/plugin");
webpackConfig.plugins.push(
	new SpriteLoaderPlugin()
);
webpackConfig.module.rules.push({
	test: /\.svg$/,
	use: [
		"svg-sprite-loader",
		"svgo-loader",
	]
});

I’m using:

• Webpack: 2.4.1
• svg-sprite-loader: 2.0.5
