Vercel thinks file doesnt exist.

Summary

Basically, i have this line of code at /api/index.js.

const jsonDataPath = legacyDataType ? "legacy.json" : "log.json"
    const filePath = path.join(__dirname, jsonDataPath);
    console.log('path is', filePath);

    if (!fs.existsSync(filePath)) {
      console.error("File does not exist:", filePath);
      return; 
    }
    fs.readFile(filePath, "utf8", (error, data) => {
      if (error) {
        reject(error)
      }
      const jsonData = JSON.parse(data)

When the jsonDataPath = 'legacy.json' it works perfectly, but when it tries to do the same thing with 'log.json' it returns this:

path is /var/task/api/log.json
File does not exist: /var/task/api/log.json

This works in both cases locally, and all the files are in the same exact directory. I dont know whats causing this, but i dont think its my code.

This is the directory:

Steps to Reproduce

To reproduce this bug, you uncheck the "legacy data?" check box which should set legacyDataType to false in the website i listed.
