CASE_EMAIL_NO_RECIPIENT
The case has no email address on file
The case has no email address on file
HTTP status 409 Conflict, code CASE_EMAIL_NO_RECIPIENT.
What it means#
A reply goes to the email on file: the case's customer's, else its contact's. This case has neither, so there is nowhere to send it. A reply never goes to an address named in the request.
What to do#
Set the case's customer (PATCH /cases/{caseId} with customerId), or a contact with an email address, then reply again.
On the wire#
