Diagnoses
The exact cause of this issue is unknown but it appears to be related to the app permissions and the K2 trust.
Resolution
On the given site collection in which the error was seen the client navigated to Site Contents and located the Appit app and clicked the ellipses which prompts a pop-up dialog box. In that box there is a second set of ellipses, click them and select 'permissions'. That will navigate you to a new page and at the bottom of that page there will be the option to 'If there's something wrong with the app's permissions, click here to trust it again". Click it.
This will rerun the K2 trust which in this case resolved the error the client was receiving.
