[Vuejs]-JHipster with vue – How to show data from the Backend in the Frontend

The problem was quite simple in the end. I did everything that was required, but I imported the wrong script in the buddy-actice.vue. If you have the same problem, you can then simply read my original comment. You will have to do the java endpoint by yourself though.

Thank you Gaël Marziou for pointing me to the right direction.
