Process Builder error "given sobject does not match type for alert: Account"
|Knowledge Article Number||000230981|
|Description||If a Process is created off Person Accounts, with Email Alert and Record Update actions, an error will result, and the debug log will show:
"given sobject does not match type for alert: Account".
When the email alert is removed, the Process works.
|Resolution||This is because Person Accounts are not supported in Workflow Rules Email Alerts.
Since Process Builder uses the same technology, it also does not support Email Alerts for Person Accounts.
