XTK-170036 Unable to parse expression '@emailFormat'
I'm seeing an error while trying to send a transactional email in the execution logs:
XTK-170036 Unable to parse expression '@emailFormat'.
'emailFormat' attribute unknown (see definition of 'head:EVTwelcome' schema).
This started happening within the past day, here's the logs showing older emails going through: https://www.screencast.com/t/H07Lljyu8dg2019-07-30_0939. I recently saw a popup saying the adobe instance I'm working in was upgraded. I'm not too sure if emailFormat is a piece specific to the instance I'm working in or not, it seems relatively generic but I'm not really sure. Is this the telltale sign of a misconfigured event/transactional email or is it more likely to be something else?
