If for a user/member the response of endpoint /v5/members/vikasrohit11/traits is [] then if we try to create a new trait for such user using POST /v5/members/vikasrohit11/traits endpoint, does not create trait (at least we can not see in GET /v5/members/vikasrohit11/traits) and there is no error log in member-api or member-processor-es both.
