We are having some difficulty with permissions. Our admin has also posted on the success board. https://success.salesforce.com/answers?id=9063A000000eB7V, she also found this same posting: https://success.salesforce.com/answers?id=9063A000000l9eC I am posting here to see if there are any devs/admins on here that have run into this issue as well.
We have a process that is called from a platform event, which sends a visualforce email template in an email alert. It seems like the Automated Process user, which is the user that triggers the Platform Event, does not have access to the email template's visualforce controller. Is there any way to give access to the controller to that user?
