The authors of an enterprise-ready webhooks sending service called Svix share their experience with a unexpected error in JSON decoding, which caused errors in their code when trying to convert the payload from one generic "JSON value" representation to another. The issue was resolved by updating the code to handle the specific UTF-16 escape sequence used in JSON, and the webhook platform was successfully delivered again within a short period of time. The authors highlight the importance of testing and assuming that all possible scenarios can be handled during development.
