I've encountered strange bug in 7.0.0-beta.32 when used with web pack when trying to set options for preset-env.

From webpack.config.js

            rules: [
                {
                    test: /\.js$/,
                    exclude: /(node_modules|bower_components)/,
                    use: {
                        loader: 'babel-loader',
                        options: {
                            presets: ["@babel/preset-env", {
                                "targets": {
                                    "chrome": 52
                                }
                            }],
                        }
                    }
                }
            ]
        }

Results in following error:

        at buildUnknownError (/node_modules/@babel/core/lib/config/options.js:79:11)

        at Object.module.exports (/node_modules/babel-loader/lib/index.js:179:20)

Error is triggered by second entry in "presets" array. Removing that entry results in everything working correctly, but trying to set any options results in errors.

babel/core version: 7.0.0-beta.32
babel/preset-env version: 7.0.0-beta.32
babel-loader version: 8.0.0-beta.0
webpack version: 3.8.1

Hey @cyberalien! We really appreciate you taking the time to report an issue. The collaborators
on this project attempt to help as many people as possible, but we're a limited number of volunteers,
so it's possible this won't be addressed swiftly.

If you need any help, or just have general Babel or JavaScript questions, we have a vibrant Slack

Sorry, figured it out. Missed that preset with options should be in nested array.

Correct code:

                        presets: [
                            ['@babel/preset-env', {
                            targets: {
                                chrome: 52
                            }
                        }]
                        ]
                    }
