Hi,

This is my error code:
404: NOT_FOUNDCode: NOT_FOUNDID: arn1::klvwr-1752237780908-7356655bf710

This is my build log:

This is my vercel.json:

{
“routes”: [
{
“dest”: “/api/$1.js”,
“src”: “/api/(.*)”
}
],
“version”: 2
}

Thanks in advance.

There’s another community post with 404 debugging tips that might be helpful. Please give these solutions a try and let us know how it goes.

A human should be around soon to offer more advice. But you can also get helpful information quickly by asking v0.

Are you having trouble reaching your python functions? I notice the vercel.json you show is mapping to JS files in the API, is that correct?

{
  "version": 2,
  "routes": [
    {
      "src": "/api/(.*)",
      "dest": "/api/$1.py"
    }
  ]
}

If you intend to have JS functions there and it’s a Python web app, then the most common reason is a misconfigured Build Framework setting for the project. Have you chosen the correct framework?
