Hi Experts,
I am trying to send an email for every Work Item created to submitter (CreatedBy). However, flow is failing with below error.
"message": "One or more recipients are invalid.",
"code": "ErrorInvalidRecipients",
"originalMessage": "At least one recipient is not valid.,

My understanding is, it will fail as CreatedBy is not an email address.
Question, is there a way to convert Created By to actual smtp of submitter?
