Empty blank Swagger docs for newly created microservice project

[ken4ward]

Overview of the issue

I created a new microservice project using jHipster 8, Keycloak and docker. The project contains the gateway and a microservice contanerised with docker. I accessed the project on http://localhost:8080. It works fine with the exemption that Swagger docs on this url http://localhost/admin/docs does not show anything. It is blank. This is strange and I sought the support of more knowledgable experts here.

Developing locally, Swagger docs did not show at http://localhost:8080/admin/docs
