Hi @johnzhang-microsoft I can't find maxSurge in the python SDK here(Azure/azure-rest-api-specs#21253 (comment)), 2022-11-01 folder does not exist, could you please provide a private package containing maxSurge for me to develop. And azure cli requires publish SDK, so please release it on pypi as soon as possible.

Hi @PARADISSEEKR . There were holidays in the USA, so the 2022-11-01 API release master needed to wait. He just submitted SDK generation for 2022-11-01 for python today. Should be available by end of this week or beginning of next week. Will that work?
