Data save error: Access denied. You do not have permission to perform this action or access this resource

Issue

When a user attempts to save a change to a form or complete an action by clicking on a button, they receive the following error:

Data save error: Access denied. You do not have permission to perform this action or access this resource

Resolution

This issue is generally caused by the user having insufficient access to one or more lists. In order to edit a form a user must have at least Contribute access to the following:

1. The main list that the form is configured on
2. Any linked lists used within the main form

Additionally, you must ensure that you do not enable Item-level Permissions on the lists. This setting permits you to restrict what users can view, edit and create within a list. If you need to enable this setting you must ensure that all the users that you wish to permit to edit the forms have at least the “Cancel Checkout” permission on the lists. This permission (which is also known as “Override list behaviors”) is available with the following permission levels by default (Full Control, Design, Approve & Manage Hierarchy). Any users or groups that are granted this level of access to a list will be able to view and edit all data. When we build apps using the Sintel Apps platform we typically do not use Item-level permissions.
