So this is always defined right? We don't need to create one for a user if it's not defined?

yes, hono has a default error handler: https://github.com/honojs/hono/blob/bb7afaccfd5b6b514da356e069f27eb5ccfc0e3b/src/hono-base.ts#L36

Our cloudflare SDK captures fetch exceptions in the catch block. But hono never reaches this block where we send exceptions.
hono processes errors with their
onErrorfunction (orerrorHandler) and we need to capture the exception there.This PR wraps the
errorHandlerof hono.Will create an E2E test in another PR.
