I'm getting the following error when trying to send an email to {{lookupObjects.Business Owner}}:
"Could not send email, the 'To' address field is empty. If you have referenced a field it may be empty."
I'm not sure why I'm getting this error because when I replace {{lookupObjects.Business Owner}} with my work email the email is sent with nonissues. If you look at the screen shot I'm also calling {{lookupObjects.Name}} in the subject and when when I use my work email, the object name is populated in the subject line, no problem.
