Program in server actions cannot bundle the correct static file

Help
1 
const csvFilePath = path.join(process.cwd(), 'prices.csv');

export const priceTable = await readCSV(csvFilePath)

When I use process.cwd() to get a CSV file, if this part of code is in server actions, the bundler will not correctly bundle the target CSV file. In Vercel it will raise a file not found runtime error.

If this code in the normal page router api route or app router API route, it works fine.

I assume it is some issue of vercel nft https://github.com/vercel/nft . Anyone has some idea?

Hi @bxclib2, after digging in deeper and help from our team. I was able to solve this issue by using the outputFileTracingIncludes option to explicitly include the data directory:

import type { NextConfig } from "next";
 
const nextConfig: NextConfig = {
  /* config options here */
  outputFileTracingIncludes: {
    '/': ['./src/data/*']
  }
};

This should solve the issue for you as well.
