Undefined property: stdClass::$diagnosticCode

[markimpmc]

Today the following exception was thrown:
Undefined property: stdClass::$diagnosticCode

in the file jdavidbakr/mail-tracker/src/RecordBounceJob.php line 73

Searching the AWS SNS documentation, apparently, the diagnosticCode property is not always sent:

diagnosticCode

The status code issued by the reporting MTA. This is the value of the Diagnostic-Code field from the DSN. This field may be absent in the DSN (and therefore also absent in the JSON).

The following is an example of a bounce object.

{
   "bounceType":"Permanent",
   "bounceSubType": "General",
   "bouncedRecipients":[
      {
         "status":"5.0.0",
         "action":"failed",
         "diagnosticCode":"smtp; 550 user unknown",
         "emailAddress":"recipient1@example.com"
      },
      {
         "status":"4.0.0",
         "action":"delayed",
         "emailAddress":"recipient2@example.com"
      }
   ],
   "reportingMTA": "example.com",
   "timestamp":"2012-05-25T14:59:38.605Z",
   "feedbackId":"000001378603176d-5a4b5ad9-6f30-4198-a8c3-b1eb0c270a1d-000000",
   "remoteMtaIp":"127.0.2.0"
}
