Webhook could not send data , might be issue from vercel

Could you elaborate your situation so we can advise better?

Hi, so I am building the nextJs application where I am using clerk to make a complete login/sign-up feature, to send the user data from clerk to MongoDB atlas, I am using webhook(it is available on clerk), but the issue is when I am doing the login or sign up on the web page, the data is showing on clerk but no on MongoDB and my code is being deployed on vercel, is there a possibility that deployment is not right, or anything from the vercel side is wrong because I do not see any error in my console or terminal at all, I can share the route.ts file which is responsible for this whole flow , somewhere I was suggested that vercel authentification feature might be the reason for this issue. kindly help, thanks!!
