[webpack] DevTools failed to parse SourceMap Warning

[MalpenZibo]

Description

There's a lot of warning regarding - DevTools failed to parse SourceMap: {sourcemap path}

Possible solution

This problem could be resolved configuring webpack with devtool: "eval-source-map".

Workaround

Configure webpack with devtool: "eval-source-map" locally. In a Bento like app this could be done by adding in Config.js a devTool: t.string config option.

example:

const t = require('io-ts');

module.exports = t.type(
  {
    bundle: t.type({
      STUFF
    }),
    devTool: t.string
  },
  'Config'
);

And in production.json/development.json/local.json set that option with `"devTool": "eval-source-map":

{
  "bundle": {
    STUFF
  },
  "devTool": "eval-source-map"
}
