Reproducing the Issue

  1. Logon to the instance.
  2. Navigate to Admin Center > Set User Permissions > Manage Permission Roles.

  4. Click any permission role.
  5. While loading the screen Permission Role Detail, system gives error message stating 'Assertion failed: invalid field structure for data model'.




  • The error on RBP mainly occurs due to configuration issue in the data model specific to company instance.
  • Any kind of misconfiguration may lead to such error message.
  • For example - Two elements in data model are having same id or few fields are expected to have at least a value which is not in place.



  • Review data-model configuration for elements with duplicate ID's.
  • A common mistake made would be to have a background-element and a standard-element with the same ID in the data-model. Example:

    • One standard element:
      <standard-element id="talentPool" required="false" matrix-filter="false">

    • Further down, a background-element with same ID:
      <background-element id="talentPool" type-id="60">
  • If a duplicate element ID has been found, amend one of the ID's and re-import the data model.


  1. Customers are requested to log an incident following the published guidelines with snapshot of the error screen.
