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.
3. The Node.js version does not match this frontend. Use Node 16 for the webpack build.

Building the client side code again

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

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 ./mvnw or using your IDE
