Namex Emailer shows Errors in the Logs

Namex Emailer shows Errors in the Logs when it receives the event from namex pay. However, the email was sent successfully. It happened when the service tries to save the event. Please investigate if there are other cases cause this.

the json event send from namex-pay is different from others: namex-pay sends event to emailer: {'request': {'header': {'nrNum': 'NR 5668068'} but the codes in emailer get nrNum from here nr_num = ce.data.get("request", {}).get("nrNum", None). That is why it always gets nrNum=None

Start by tracing the Namex Emailer event-save path and compare the namex-pay payload shape with the other event variants. Confirm how nrNum is read and identify the other cases mentioned in the issue; done means successful emails no longer produce erroneous save errors and supported event shapes are handled consistently.
