I have a process builder that calls Apex "Run DDP" to send an auto-response.
Package and Delivery Option (Email) are configured with the correct email template. I'm getting an error when the process builder runs.
"Error sending Salesforce email for (Case:<<Id here>>) (required_field_missing): Missing targetObjectId with template (ExternalError)"
What am I missing? I do not have contact selected, I need this to be sent to the "Additional To" pre-defined email.
