Answer 1

Another solution in case it helps: in my case, the problem was that I had a @RequestMapping("/xxx") at class level (in my controller), and in the exposed services I had @PostMapping (value = "/yyyy") and @GetMapping (value = "/zzz"); once I commented the @RequestMapping("/xxx") and managed all at method level, worked like a charm.
