I’m injecting custom attributes via genesyscloud.messaging.setGuestAttributes before the widget initializes, but they disappear on the first message send. The genesyscloud.messaging.connect call returns success, yet the webhook payload only shows the default guest ID. Here is the config object: { name: 'John', email: 'john@example.com', custom: { userId: '123' } }. The attributes are there in the browser console right before connect, but gone in the server-side event. What am I missing?
