Missing `userId` field on `HumanUser` API v2 responses

When calling the endpoint

POST https://$CUSTOM-DOMAIN/v2/users

POST https://$CUSTOM-DOMAIN/v2/users

on Zitadel API v2,

result[x].human

result[x].human

fields of type

HumanUser

HumanUser

previously contained a

userId

userId

field. This no longer seems to be the case. Is this normal and expected? Because the documentation always indicates the presence of this field.
