The webhook is not triggered when a webinar event occurs

We are facing an issue with validating a URL that uses the POST method. Despite having all the necessary code, the particular method is not being invoked during any webinar events, even though the method is live. We have checked the method invocation overview and log messages.

Additionally, we have tested calling the method to retrieve data when an event is triggered in Zoho CRM, and it is not successfully triggered.

However, when I replicate the Code on my own basic account with meeting events, it is triggered successfully.

We are trying to trigger the event from Development environment of Zoom Market Place.
