Nitro and tRPC in vercel-edge

Hey there! I hope this is the right place to ask for help.
I am trying to deploy an application with Nitro and tRPC with the vercel-edge preset.
I am getting a weird proxy error when I deploy it without making any changes to how tRPC is handled.

TypeError: 'getOwnPropertyDescriptor' on proxy: trap reported non-configurability for property 'setTimeout' which is either non-existent or configurable in the proxy target

I think I need to use the 
fetchRequestHanlder
 as described in the tRPC documentation for 
Fetch / Edge Runtimes
 https://trpc.io/docs/server/adapters/fetch
They provide examples for Next.js, Remix, and SoldStart, but not Nuxt/Nitro.
Nitro uses 
IncommingMessage
 and 
ServerResponse
, while the 
fetchRequestHandler
 expects a 
Request
 and returns a 
Response
.

My initial, naive approach was to simply map back and forth between the two using these utilities I found for astro: https://github.com/withastro/astro/blob/2dca81bf2174cd5c27cb63cb0ae081ea2a1ac771/packages/integrations/vercel/src/serverless/request-transform.ts#L2

But again I am getting errors that seem to stem from Nitro using 
node-fetch
 under the hood? I am not experienced enough with the edge runtime or nitro to completely understand why it would not work and what needs to happen to make tRPC and Nitro on edge work together.

If anyone has any pointers or if anyone has a repo of a Nuxt/Nitro project that uses tRPC on the edge that would be awesome!

Thanks already for your help!

You can create a tRPC server within any edge runtime that follow the WinterCG, specifically the Minimum Common Web Platform API specification.
