An error has occurred :-(

Usual error causes

1. You started the application from an IDE and you didn't run npm start or npm run webpack:build.
2. You had a network error while running npm install. If you are behind a corporate proxy, it is likely that this error was caused by your proxy. Have a look at the error logs, you will probably have the cause of the error.
3. You installed a Node.js version that doesn't work: please use an LTS (long-term support) version, as it's the only version we support.

Building the client side code again

If you want to go fast, run to build and run everything.

If you want to have more control, so you can debug your issue more easily, you should follow the following steps:

1. Install npm dependencies with the command npm install
2. Build the client with the command npm run webpack:build or npm start
3. Start the server with or using your IDE
