Webhooks failing with Error 500

I’ve been randomly getting Error 500’s on various webhook calls resulting in the subscription being paused. I’m trying to figure what the issue could be as our testing environment in the sandbox is using the same code and not seeing these failed attempts. Here is an example of the JSON from the webhook details:
