An error has occured :-(

Usual error causes

1. You started the application from an IDE and you didn't run npm start or npm run 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 Angular 7 error logs, you will probably have the cause of the error.
3. You installed a Node.js version that doesn't work with Angular 7: 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 ./mvnw 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 build or npm start
3. Start the server with ./mvnw or using your IDE
