Unable to Execute Go Serverless Function

[jcald1]

I've created an app with a JS (Node.js) serverless function in /pages/api/seed-data.js. I created a PR and on the Vercel CI server (https://commercial-real-estate-datadeck-jc-git-feature-go-basic.jcald1.vercel.app/), I'm able to access that API route. (/api/seed-data)

I also included the Go sample file from https://vercel.com/docs/v2/serverless-functions/supported-languages#go in that same directory.

I expected that a call to /api/date to work. However, I'm getting a 404.

As a related question, is it possible to test such a serverless endpoint locally? Do I need to run vercel dev and have installed Go locally on the host first? Or would it run the Go code in a container so the host doesn't need Go to be installed?

Thank you for sharing this issue with us!

Next.js natively only supports Node.js Serverless Functions. Those are the ones you place in pages/api.

If you want to write Serverless Functions in Node.js and Go, Next.js won't help there, unfortunately. You'd have to place the Serverless Functions inside the api (not pages/api) directory, which makes Vercel take care of them.

And yes, then you'd have to run vercel dev. You can read more about how to use Serverless Functions on Vercel here.
