Technical info

I'm using laravel 5.7

babel config (babel.config.js)

module.exports = function (api) {
    api.cache(true);

    const presets = [
        [
            "@babel/env",
            {
                useBuiltIns: "usage",
                corejs: 3
            },
        ],
    ];

    const plugins = [
        ["@babel/plugin-transform-runtime", {
            corejs: 3
        }]
    ];

    return {
        presets,
        plugins
    }
};

I'm using Angular and experienced the same error, seems to be something to do with not having "a global regeneratorRuntime" - parse-community/Parse-SDK-JS#740

Installing the babel polyfill (npm install babel-polyfill) and then adding it to my polyfills.ts solved the issue, not sure how you'd do it in Laravel but hope I've pointed you in the right direction.

For Laravel, you should install 'babel-polyfill' npm install babel-polyfill and then put it at the top of the main js file, 'import "@babel/polyfill";' .
