FIXED. Verified on 5.9.5.3.20181023135339_256263f.

Steps taken to verify the BZ:
1) Create a new domain, `domain_1`.
2) Create a Method, let's say `method_1`.
3) Create an instance, let's say `instance_1`.
4) Create a Dialog with one static element with some default value, and one dynamic element with the endpoint pointing to `method_1` which returns default value.
5) Create a Catalog, say `catalog_1`.
6) Create a Generic Catalog item under the newly create Catalog, say `catalog_item_1`.
7) Get the `service_catalog` id and `service_template` id.
8) Send the request.

Edit https://bugzilla.redhat.com/show_bug.cgi?id=1639413#c4 :

I tested with 2 queries, both of which worked fine.

1) POST: https://<ip_address>/api/service_catalogs/:id/service_templates/:id
   Query: { "action": "order"}

2) POST: https://<ip_address>/api/service_catalogs/:id/service_templates/
   Query: { "action" :"order",
            "resources" : {
                   "href" : "https://<ip_address>/api/service_templates/:id"
                    }
          }
