Re: I am getting validation error message creating sandbox tester account.

I am having the same issue. Seems like Apple made some changes, also deleted bunch of old sandbox accounts. I am unable to create a new one now, getting "There are one or more validation errors below." without any indication of what the error is.

Apple fixed the issue today - Now able to create a Sandbox Test account and use the account successfully. However, site is not updated with newly created Sandbox Test account (it doesn't display on the list of accounts).

Creating Sandbox Test account now working as expected for me. Able to create new accounts and newly created account displays on the list.

I'm having the same problem. All data is valid. Nothing is flagged as invalid, but the error message appears, and I cannot create the tester.

I'm having the same problem.

This whole thing is just so irksome. Why do I need a bulletproof password and secret question and answer for a test account? This is such a waste of time

I'm having the same problem.

!!!!!!!! There are one or more validation errors below.

Having the same problem here. Serioursly Apple? Errors within 10 fields? Fix it!

Same issue. I tried reloading the page and looking for a confirmation email. Nothing worked. What worked for you guys?

Same issue happening to me.

Tried using Safari and turning off VPN, still no luck.

What an absolute joke.

Can't believe this. Rookie developers don't do this.

I've the same issue. Please fix this ASAP !!!!!

+1 I have the same issue.

I was getting the same error due to different reason.

Email address that has never been used as an Apple ID to purchase iTunes or App Store content, nor associated with any existing Apple ID. Consider creating a dedicated email address for each sandbox tester.

Reference Link: https://help.apple.com/app-store-connect/#/dev8b997bee1

My input email was already an Apple ID. So I created another email address just for this sandbox tester.

Same issue here!

Can not create a sandbox user account.

The email I used address that never was associated to an Apple ID.

It looks like it doesn't like + in the email address. Also the password needs to be more complex, at least one uppercase, one lowercase and one number. So you'll need to create a new gmail account or add . anywhere in the username part of the email address, for example usernam.e@gmail.com instead of original username@gmail.com (emails will be delivered to the original email).

+1 here, I cannot add a user as an app manager in Apple store connect, it says "There are one or more validation errors below."

My account type is individual.

+1 Facing the same issue. Cannot invite developer too

Facing the same issues. Can not do internal testing because of this, and now need to wait review. Please. fix.

same here!

Apple please fix the issue.

I am facing the exactly same problem. I inspected the network requests and in the POST request "https://appstoreconnect.apple.com/iris/v1/userInvitations" the response is:

{
  "errors" : [ {
    "id" : "dd7b9258-d992-41db-a9fc-fdd18557db80",
    "status" : "409",
    "code" : "ENTITY_ERROR.ATTRIBUTE.INVALID",
    "title" : "The provided entity includes an attribute with an invalid value",
    "detail" : "Individual can't have provisioning privilege.",
    "source" : {
      "pointer" : "/data/attributes/provisioningAllowed"
    }
  } ]
}

I tried with an Apple ID associated account and one that is not associated. Also, the developer account that I am trying to give access didn't not have two-factor authtentication enabled.

Same for me, I can't grant the access to a new developer or administrator.The same error is appearing "there are one or more validation errors".

Now I'm getting the same issue...
Anyone can tell me the solution for that?

+1... I've been having this for days and can't find a solution.

I tried it and was able to make it work. 

1) There may be a limit of 10 test users.  I am not sure but I was able to add a 10th test user.

2) I needed to use a valid email address that had never been used before as an AppleID.  Using a previously used email address with "+1" did not work.

3) I have access to do this as both an "Admin" and an "Account Holder" - I do not know which of these was actually required.

I've just tried: looks like it is fixed now! It worked even with an appleID-email.

Same here. Tried on Safari, Chrome,Firfox nothing works!

Selecting birthdate date goes wrong with wrong labels! (this cant be missed by a tester om )

Submitting the form gives always a sick making error! really sad to see this happening at Apple!
