When running a webpack build, webpack throws the following warning:

DeprecationWarning: loaderUtils.parseQuery() received a non-string value which can be problematic, see https://github.com/webpack/loader-utils/issues/56
parseQuery() will be replaced with getOptions() in the next major version of loader-utils.
  at Object.parseQuery (/var/www/prod/node_modules/loader-utils/index.js:78:3)

• getOptions - the only way to get the loader options. It will look like this:
