The template jira-service-management-portal-request-create-property-panel template is not relaying information within the extension context to the portal detail extensions, what might be the cause?

"extensionContext":{
"type":"jiraServiceManagement:portalRequestDetail",
"portal":{"id":1},
"request":{
                   "typeId":2,
                    "key":"SAMPLE"}
