generator-jhipster: Jhipster tutorial application crashes when I access from the browser.

Overview of the issue

I followed the video tutorial using the default options for jhipster. The application built and starts up without an error. However, when I try to access the application at http://localhost:8080, I get the following stack trace:

    Application 'dipity' is running! Access URLs:
    Local:          http://localhost:8080/
    External:       http://192.168.1.78:8080/
    Profile(s):     [dev, api-docs]

Motivation for or Use Case

I am trying to evaluate jhipster for a project, but can’t get the tutorial application to work.

Reproduce the error

1. Follow the steps in the tutorial on Windows 11.
2. Run the application using ./mvnw
3. Access the app from your browser…
