disabling transpiling async-await in production build

[ducin]

Hello,

TL;DR; which option should I set to disable transpiling async/await with regenerator in a production build?

I'm running a CRA-based application with default settings.
Recently we've experienced a need to debug a production build on a file that is based on async-await. The CRA's production build is configured to transpile A/A down to ES5 using regenerator package (I think it's done via one of babel plugins). The issue is that the code on production and our original code (available through sourcemaps) are so different that debugger jumps across the file, making ordinary debugging in the browsers pretty useless.

So far I've tried a couple of different settings to alter CRA's babel settings, but none of them helped, asyncToGenerator.js is still there :(

config-overrides.js:

const { override, addBabelPresets, addBundleVisualizer } = require('customize-cra')

module.exports = override(
  ...addBabelPresets(
    ["@babel/preset-env",
      {
        "targets": {
          "browsers": ["last 1 version"]
        },
// not sure which name should I put here, various links found on the web relate to various babel versions, I'm using `@babel/[email protected]`
        "exclude": [
          "transform-regenerator",
          "@babel/plugin-transform-regenerator",
          "@babel/plugin-transform-async-to-generator",
        ]
      }
    ]),
  addBundleVisualizer({
    analyzerPort: 8889
  }),
)

What does your package.json have for browserslist?
