Solution

Just had some time to check this issue and found a similar reported issue here:
electron/electron#22996 (comment)

This is an issue with Electron, which incorrectly resolves the sourceMappingURL generated by Webpack devtool. So, you need to correct the path.

Steps

Option1: Update preload.js

If you update the following code in preload.js

//# sourceMappingURL=preload.js.map

with

//# sourceMappingURL=file:///location/to/preload.js.map

The issue will go away. This applies to both dev and prod.

Option 2: Update webpack.common.js

Add devtoolModuleFilenameTemplate to webpack.common.js:

module.exports = {
  //...
  output: {
    ...
    devtoolModuleFilenameTemplate:
      'file:///[absolute-resource-path]',
  },
};

The warning will also go away.

See #938 for the fix.
