API: PUT /topics/:topicId/members/users and PUT /groups/:groupId/members/users to return HTTP 422 if any of the userId-s is not a valid email or UUID.

Overview

Initial implementation of PUT /topics/:topicId/members/users and PUT /groups/:groupId/members/users just ignore invalid UUID-s and e-mails. The shortcoming of this is that if you insert invalid e-mail/UUID, you will never know if the invites actually succeeded.
To provide adequate feedback, he input data should be validated and an error code returned.

TODO

• PUT /topics/:topicId/members/users to return HTTP 422 IF any of the userId is invalid e-mail or UUID. Update tests.
• PUT /groups/:groupId/members/users to return HTTP 422 IF any of the userId is invalid e-mail or UUID. Update tests.
• Once done, create a task OR implement a fix in the Citizen OS FE (https://github.com/citizenos/citizenos-fe) project to update our UI to show the error.

Seems still relevant, but needs further investigation on where and how to implement
