Cannot Generate a Preview when sending to workflow

I am getting an error message when I am trying to send my templates to workflow. Cannot generate a preview for ‘template name’: An unexpected error occurred. Continue packaging files? If there are errors in the template, how do I figure out what they are? I have done a preflight and do not find anything there. Can I still send it to workflow, or will that cause issues?
Thank you

Hello @diane,

According to the error “Cannot generate a preview for ‘template name’: An unexpected error occurred.” I assume that it is the best to create new Support ticket via our website as this error can occur for various reasons.
