Error: Function Runtimes must have a valid version? Deployment issue

[JadamMyers]

Summary

This is my first time deploying on Vercel. And when I run 'vercel' in my terminal I do get a URL but I also get these errors "
Error: Function Runtimes must have a valid version, for example now-php@1.0.0.
invalid_function_runtime: Function Runtimes must have a valid version, for example now-php@1.0.0."

I'm not sure what these mean, I updated to the latest version of vercel and I think my vercel.json file is correct. Would someone be able to help me make sense of this?

Additional information

// vercel.json

{
"functions": {
"api/deezer-proxy.js": {
"runtime": "nodejs14.x"
}
},
"routes": [
{
"src": "/deezer-proxy(.*)",
"dest": "/api/deezer-proxy.js"
}
]
}

It looks like you have a problem with your function config. The runtime only needs to be specified if using an unsupported runtime, so you don't need to specify Node.js here. Instead, you can set the Node.js Version on the Project Settings page.

Setting the Node.js Version did not work. Neither did setting "runtime": "nodejs" as written in the docs.

Could you post how to use node.js version 20 here?

Thanks

You can use Node v20 in your project by selecting 20.x in the Node.js Version section on the General page in Project Settings. The default runtime is nodejs so you usually don't need to specify the runtime for Node.js Serverless Functions in the /api directory.
