Failed to parse source map

[leanderseige]

I switched my project to react-scripts version 5.0.0-next.47 because of the many unpleasant warnings the latest stable version of react-scripts throws these days. This works good enough for me, however manifesto causes a lot of warnings because it could not find/parse source maps. Because manifesto seems to be the only package causing these warnings I'm bringing this up here.

WARNING in ./node_modules/manifesto.js/dist-esmodule/Thumbnail.js Module Warning (from ./node_modules/source-map-loader/dist/cjs.js): Failed to parse source map from '/Users/seige/seige.digital/strollview-editor/node_modules/manifesto.js/src/Thumbnail.ts' file: Error: ENOENT: no such file or directory, open '/Users/seige/seige.digital/strollview-editor/node_modules/manifesto.js/src/Thumbnail.ts' @ ./node_modules/manifesto.js/dist-esmodule/internal.js 25:0-28 25:0-28 @ ./node_modules/manifesto.js/dist-esmodule/index.js 1:0-27 1:0-27 @ ./src/components/ImportLoader.js 10:0-37 102:18-37 @ ./src/App.js 8:0-56 35:39-51 @ ./src/index.js 7:0-24 14:8-11
