An error has occurred :-(
                Usual error causes
                
                    - 
                        You started the application from an IDE and you didn't run npm startornpm run webapp:build.
- 
                        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 JHipster error logs, you will probably
                        have the cause of the error.
- 
                        You installed a Node.js version that doesn't work with JHipster: 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:
                
                    - Install npm dependencies with the command npm install
- 
                        Build the client with the command npm run webapp:buildornpm start
- Start the server with ./mvnwor using your IDE
