I send servicespecification GET request to NBI El-Alto release but it fails with the below message. 

Request:
_http://Elalto_LB:30274/nbi/api/v4/serviceSpecification/66a66cc3-178c-45fd-82c2-494336cb3665
_
Response:
{
    "timestamp": 1573482985288,
    "status": 500,
    "error": "Internal Server Error",
    "message": "No message available",
    "path": "/nbi/api/v4/serviceSpecification/66a66cc3-178c-45fd-82c2-494336cb3665"
