End-of-call-report without server credential

I observed following inconsistency when an end-of-call-report is sent:

When the endedReason == 'twilio-failed-to-connect-call', then the set server credential is missing. For other ended reasons on the same assistant, the end-of-call-report includes the right credentials as expected.

Background:
  • I used the new 'server.credentialId', not the 'isServerUrlSecretSet'.
  • I received the end-of-call-report with the correct credentials at my server URL as expected when testing via a webCall (or live examples, see below).
Data:
  • Example with error observed: call ID: e573b330-ac35-4872-988e-142bf70742e1
  • Example without error: call ID: 688af10c-4a3e-457f-b6ae-1518e5715beb
  • Assistant ID: b41baaac-3770-4619-a90e-5278d1f06b80
