Edit: Updated post to correctly reference issue with request body, not payload.
I tested the beta version of EventSub with the same request body in the documentation and having the moderator:read:followers scope but received the following error:
{
"error": "Bad Request",
"status": 400,
"message": "unknown validation error: Key: 'SubscriptionCondition.moderator_user_id' Error:Field validation for 'moderator_user_id' failed on the 'required' tag"
}
This was the reason I thought there was supposed to be a beta/v2 version request body example as it seems the condition is now moderator_user_id instead of broadcaster_user_id.
