Invalid member: user ID cannot be empty.

Error message

Invalid member: user ID cannot be empty.

What it means

_member_value validates that each SCIM group member carries a non-empty value (the user id); an empty or whitespace-only value is unresolvable, so the request is rejected with 400 before any classification happens. At-fault input is SCIMMember.value empty/blank.
