Group name validation and email validation are not consistent
When creating a group, group name is validated against expression: "^[A-Za-z0-9{}.-]{3,128}$" At the same time, when executing get members request, the email is validated against expression: "^[A-Za-z0-9+.-]{1,256}+@[A-Za-z0-9+_.-]{1,256}$"
Such inconsistency caused existence of such group: {{new_creatordatagroup}}@some-partition.enterprisedata.cloud.some-domain.com, and members of such group could not be retrieved.
