Did you mean '2019-03-01-hybrid' ?

Examples from AI knowledge base:
az cloud register -n MyCloud --cloud-config @"cloud.json" ("cloud.json" supports all the endpoint and suffix options in camel case or the JSON output format from `az cloud show`. See the example content below.) *** "endpointActiveDirectory": "https://login.microsoftonline.us", "suffixAcrLoginServerEndpoint": ".azurecr.us" *** or *** "endpoints":*** "activeDirectory": "https://login.microsoftonline.us" ***, "suffixes":*** "acrLoginServerEndpoint": ".azurecr.us" *** ***
