Internal Server error when doing a POST with invalid emails on /v1/user/emails

[ludovicianul]

Description

While doing some fuzzing using https://github.com/Endava/cats I discovered an issue for the /v1/user/emails endpoint. Doing a POST with an invalid email address results in a 500, rather that something more meaningful.

You can reproduce the issue using (just replace $token with your own token):

cats replay Test228.json

Or using the payload:

{
  "emails": [
    "yCUjse4J",
    "yCUjse4J"
  ],
  "catsFuzzyField": "catsFuzzyField"
}
