It appears that the config variables for Mockserver are sometimes used differently, e.g. sometimes they are used independently: ``` *** Keywords *** Create Sessions Start Process java -jar ${MOCK_SERVER_JAR} -serverPort ${callback_port} alias=mockInstance Wait For Process handle=mockInstance timeout=5s on_timeout=continue Create Mock Session ${callback_uri}:${callback_port} ``` SOL003 vnf inicator api variables: ``` ${callback_uri} http://localhost ${callback_port} 9091 ``` while some other times: ``` Send Post Request for VNF Package Subscription Log Trying to create a new subscription Set Headers {"Accept": "${ACCEPT_JSON}"} Set Headers {"Content-Type": "${CONTENT_TYPE_JSON}"} ${template}= Get File jsons/subscriptions.json ${body}= Format String ${template} callback_uri=${callback_uri} callback_endpoint=${callback_endpoint} vnfPkgId=${vnfPkgId} **<- assumes port is included in the uri ** Run Keyword If ${AUTH_USAGE} == 1 Set Headers {"Authorization": "${AUTHORIZATION}"} POST ${apiRoot}/${apiName}/${apiMajorVersion}/subscriptions ${body} ${output}= Output response Set Suite Variable ${response} ${output} Run Keyword If ${NFVO_CHECKS_NOTIF_ENDPOINT} == 1 ... Check Notification Endpoint Create Sessions Pass Execution If ${NFVO_CHECKS_NOTIF_ENDPOINT} == 0 MockServer not started as NFVO is not checking the notification endpoint Start Process java -jar ${MOCK_SERVER_JAR} -serverPort ${callback_port} alias=mockInstance Wait For Process handle=mockInstance timeout=5s on_timeout=continue Create Mock Session ${callback_uri} **<- assumes port is included in the uri** ``` My understanding would be that the correct version to be supported is the one with `${callback_uri}:${callback_port}`.
