I observed sometimes a data hook will not properly execute. On average the data hook will work.
How the one data hook works is, a item is inserted into a data set. It triggers an update to the same data set, then an email is sent via sendgrid.
When there is an issue, the data is not updated and a trigger is not sent. When I see this, I delete the row from the table and run the operation again and I can't repeat the issue.
This seems to be a random occurrence.
