MEC011: Test case TC_MEC_MEC011_SRV_APPSAQ_004_BR does not return 400 as expected
Trying to create a new service with the following payload does not provide an error (with HTTP 400 code) as expected, but the service is created without a problem. Suggest checking how the payload is processed.
```
{
"serName": "NEW_SERVICE_NAME",
**"a_version": "v2.0",**
"state": "INACTIVE",
"serializer": "XML",
"serInstanceId": "3F897E85-ABCD-FFFF-A957-FCF0CCE649FD"
}
