Thank you for the response and I apologize for misreading the other help thread.
I deployed a project that contains Node & Python serverless functions to Vercel and both endpoints work. However, when developing locally using the Vercel CLI I keep getting, this huge error:
when accessing http://localhost:8071/api/node
vercel dev --listen 8080
Vercel CLI 41.2.2
> Ready! Available at http://localhost:8080
Server is running on http://localhost:3000
file:///C:/Users/o0/.bun/install/global/node_modules/@vercel/node/dist/dev-server.mjs:1133
return listener(req, res);

at processTicksAndRejections (node:internal/process/task_queues:95:5)
This error originated either by throwing inside of an async function without a catch block, or by rejecting a promise which was not handled with .catch(). The promise rejected with the reason:
Error: Command failed: taskkill /pid 1808 /T /F
ERROR: The process "1808" not found.

I changed up the ports because I thought it might have to do with ports being in use. Long errors, I just wanted to share but maybe I’m just tired since its late here, I’ll take a look at these tomorrow and update.
Note: I installed the Vercel CLI using Bun, I don’t know if that might be the issue.
