500 error code when trying to create a new Sandbox user

Hi,

I'm trying to add a new Sandbox User in App Store Connect. Users and Access -> Sandbox Testers -> +. I filled all needed information and got the 500 error.

Request URL: https://appstoreconnect.apple.com/sandbox/v2/account/create
Request Method: POST
Status Code: 500 

On the UI, no error messages at all.

Help please.

I'm encountering the exact same issue. No error in the UI, error 500 with a json object :

{
  "validationResults": [
    {
      "field": null,
      "localizedField": null,
      "validationRuleName": null,
      "messageKey": null,
      "error": null,
      "propertyName": null,
      "errorShortMessage": null,
      "errorFlag": null,
      "errorString": "An unknown error has occurred.",
      "errorNumber": -21607
    }
  ],
  "status": null,
  "code": null
}

same problem here... tried with two different developer accounts

Same problem here. Did anyone manage to fix this? 😕

In my case, that was an email that was from a domain Apple did not like. When I switched to a more "common" account (something gmail related) it accepted my users.

I lost 3-4 hours on this issue and now I think I understand what happens.

Always when I use parts of the first name / last name in the password, I receive 500 HTTP error code.

Fix: Don't use first name / last name / email parts when you choose the password.

Avoid: First name: "Test", Last name: "User" with password "Test_123" or "User_123".
