Vapi widget - Bubble.io

Hello,

I have been using Vapi in a bubble.io website. I used the code in and HTML iFrame inside a bubble.io page.
The code is in line with the exemple in the doc : https://docs.vapi.ai/examples/voice-widget
It worked well, but since several days when I click on the icon to start the call, it is stuck in "Connecting..."
I have the following message in the console :

DOMException: Failed to execute 'postMessage' on 'Window': Invalid target origin 'null' in a call to 'postMessage'.

Any idea why ?

@Ask Inkeep : Is it possible to have the URL of the previous version of the script in order to test it ?
