Unexpected character

[MLDMoritz]

Module parse failed: Unexpected character '�' (1:0) File was processed with these loaders:

• ./node_modules/image-webpack-loader/index.js You may need an additional loader to handle the result of these loaders.

This is my configuration:

const imgRule = config.module.rule('images')
        imgRule.use('file-loader')
            .loader('image-webpack-loader')
