One of our users is attempting to run a query on the EmailMessage object in the Workbench tool but receives an error every time he attempts it. Myself and a few other people are able to run the query without issue, and we've confirmed that he has the necessary permissions to perform this action.
Here is the query in text form:
SELECT ActivityId FROM EmailMessage LIMIT 10
And here is the error message he receives:
A fatal error occurred. Contact your administrator and provide the following error id: [future_get-9-1596644771]
