Hi @Vinaykumarvuppala!

Could you try this configuration?

{
  "version": 2,
  "functions": {
    "api/app.py": {
      "runtime": "[email protected]", // or [email protected]
      "memory": 1024
    }
  },
  "routes": [
    {
      "src": "/(.*)",
      "dest": "api/app.py"
    }
  ]
}

@pawlean any update here? Does Python deployment currently work for Vercel? I am getting the same error with the following configuration (my project is currently on Node 20.x)

Error: Function Runtimes must have a valid version, for example [email protected].

{
    "version": 2,
    "functions": {
      "api/index.py": {
        "runtime": "[email protected]"
      }
    },
    "routes": [
      {
        "src": "/api/(.*)",
        "dest": "api/index.py"
      }
    ]
  }

You don't need the "runtime" property at all if you are trying to deploy Python - it's one of the built-in languages for Vercel. In fact, unless you are trying to override some of the other configuration options (like memory or maxDuration), then there is no need to have that "functions" object at all. You can delete it.
