Hi Sandy Bergman,
Thank you for reaching out to us on Microsoft Q&A forum.
Can you please specify the exact Learn Path/Module name/Exercise link where you are encountering this error?
Hi Kiran,
Sorry, it is not from a Learn Path or Module. It is from live production environment. I posted my question in the wrong forum. When sending email notifications for an Approval Workflow, I am now encountering this error.
