subscriptionServiceType is not set properly in request payload to SO :

"requestParameters": {
{{ "aLaCarte": true,}}
{{ "subscriptionServiceType": null,}}
{{ "userParams": []}}
{{ }}}

File below needs to be changed:

src/main/java/org/onap/nbi/apis/serviceorder/model/consumer/RequestParameters.java

**public void setSubscriptionServiceType(String subscriptionServiceType) {

<         this.subscriptionServiceType = subscriptionServiceType;

—

>         subscriptionServiceType = subscriptionServiceType;

    }
