This request:
curl -X GET -H "Cache-Control: no-cache" "http://localhost:8080/v1.0/FeatureOfInterest" is working well the same way than
curl -X GET -H "Cache-Control: no-cache" "http://localhost:8080/v1.0/FeaturesOfInterest"
It should only work the second request, in plural, not the one in singular
