I'm building out some flows with the rest api and all has gone well until I needed the PATCH request for [canceling a deployment](https://vercel.com/docs/rest-api/endpoints#cancel-a-deployment). This always returns a 400 and only says BAD REQUEST which is definitely not coming from the vercel api. I've confirmed that I can cancel an active deployment successfully using postman, just can't get it to work in my application. Something is stopping my request in the browser. Has anyone experienced this? All the other GET/POST requests I've used from vercel in this project work well. Request headers all seem to match the ones that worked in postman. What else should I try?
