End-to-end test fails when trying to edit a L2VPN with incomplete body

[gretelliz]

Testing the following example returns 201: Connection published

        # existing L2VPN -> key

        api_url = SDX_CONTROLLER + '/l2vpn/1.0'
        payload = {
            "name": "Test L2VPN request",
            "endpoints": [
                {"port_id": "urn:sdx:port:ampath.net:Ampath3:50","vlan": "300"},
                {"port_id": "urn:sdx:port:tenet.ac.za:Tenet03:50"}
            ]
        }
        response = requests.patch(f"{api_url}/{key}", json=payload)

-> Body incomplete: vlan attribute is missing on an endpoint
The return code 400 should be obtained
"400: Request does not have a valid JSON or body is incomplete/incorrect"
