Account.Retrieve SSJS core function has stopped working

Question

I'm having issues with the Account.Retrieve() SSJS core function. I was previously able to use this code to retrieve all Business Units in an Enterprise account:

<script runat=server>

Platform.Load('core', '1');

var filter = {
  Property: 'Name',
  SimpleOperator: 'NotEquals',
  Value: null,
  QueryAllAccounts: true
};

var getBUs = Account.Retrieve(filter);

Write(Stringify(getBUs));

</script>

While this script works in some enterprise accounts, it is now returning an empty array in other accounts. It used to work consistently across all Marketing Cloud accounts. I've tried changing the filter to include a BU name or MID, but it's still empty. I'm wondering if anyone else has experienced this and can suggest a workaround?

partially copied from comment: code works for me, stack51.

to narrow down if the operator is (or became) the problem, try a filter that relies on operator equals but also assumes nothing, like

filter = {  
Property: 'IsActive'
    ,SimpleOperator: 'equals'
    ,Value: '1'
    ,QueryAllAccounts: true
};

• potential workaround or at least something to find our what the issue is:

retrieveRequest using SOAP API (which of course wont retrieve a JSON but an xml), just tried this successfully on stack7:
