After updating to version 7.1.0 (From 6.5.0) we get the following error:

WARNING in ../../node_modules/@turf/jsts/dist/jsts.min.js
Module Warning (from ../../node_modules/source-map-loader/dist/cjs.js):
Failed to parse source map from '/node_modules/@turf/jsts/dist/jsts.min.js.map' file: Error: ENOENT: no such file or directory, open '//node_modules/@turf/jsts/dist/jsts.min.js.map'

Could the sourcemaps be included?
