Microservice APIs returning empty response (master)

Overview of the issue

Microservice APIs return empty responses (generated with master branch). I’m guessing it affects all Zuul routes since getting the account from the UAA is also broken.

Motivation for or Use Case

Generate a working microservice architecture

Reproduce the error

Generate a gateway Generate a microservice Generate an entity on the microservice (then on gateway) Start registry, gateway, microservice Attempt to access entity page

In browser developer tools, you can see on the network tab the response is null. You can also see errors logged to the console, such as core.js?09c9:15713 ERROR TypeError: Cannot read property 'length' of null at JhiParseLinks.parse (ng-jhipster.js?8ee9:1971)

Don’t think so

Suggest a Fix

Unsure, maybe related to SB2.1? Only affects master

JHipster Version(s)

Master, v5.8.2 works fine.

Finally got it ! The problem comes from this file: https://github.com/jhipster/generator-jhipster/blob/master/generators/server/templates/src/main/java/package/config/lazy/LazyInitBeanFactoryPostProcessor.java.ejs

If I disable it for dev, it works. Ping @jdubois as you coded this file. Can you help us on this ticket ?

So it seems we just need to add private Class<?>[] exclusionList = {ZuulFilterInitializer.class}; for gateway apps. As solved here: https://github.com/mraible/jhipster-ms-oidc-improved/pull/1
