Using WebSockets with PRC in Cloudflare Worker
PRC can communicate with workers and Durable Objects via serializable objects, but Response, including WebScoket, is not considered Serializable, so miniflare does not work. The same thing happens with v8 isolated.

Setting DurableObject from wrangler.toml results in an error.
DurableObjects created with CloudflareWorker can be registered with CloudflarePages. However, if I use wrangler pages download config <project-name> to create wrangler.toml and then deploy again, `This namespace no longer exists and can not be read from or written to. Please try using a different namespace.
