Sourcemap and break points in Chrome don't work

Question

I'm trying to place breakpoints in transpiled code that has a source map, but every time I press a line to place a breakpoint, it cancels immediately.

Like here:

Is it a problem with the webpack configuration? Should I post it?

Answer 1

In the webpack config I changed devtool: 'eval-source-map', to devtool: 'source-map', and now it works, but it generates a .map file for each transpiled file, which didn't happen before when it worked.

Edit:

also removing this from the config helped:

new webpack.optimize.UglifyJsPlugin({
  sourceMap: true,
  compress: false,
  minimize: false,
  mangle: false
}),
