Next button - does not trigger v1.avatar.exported

our RPM web integration (via i-frame) stopped triggering the v1.avatar.exported event.

We can reproduce this issue by coping the quickstart code at

https://docs.readyplayer.me/ready-player-me/integration-guides/react/quickstart

and replacing the demo value with our subdomain:

  1. Open the resulting HTML file
  2. Close the “start from template” overlay
  3. Click “Next ->”
  4. Click “Continue without signup”

The “Next ->” button displays the popup.

This results in a deadlock situation affecting our live systems.

Is this a misconfiguration on our part or did something change at RPM the last few days? How to trigger onAvatarExported
