fs.mkdir ( ./tmp ) is giving error

Problem Description

I'm making the /tmp folder to store the incoming PDF from the client.

const storage = multer.diskStorage({
    destination: (req, file, cb) => {
        fs.mkdir('./tmp', { recursive: true }, (error) => {
            if (error) {
              console.error('Error creating folder:', error);
            } else {
              console.log('Folder created successfully');
            }
            cb(null, './tmp');
        });
    },
    filename: (req, file, cb) => {
        console.log("File uploaded");
        console.log(file);
        cb(null, `${file.originalname}`);
    }
});

After doing all the operations, I'm deleting the /tmp folder

const folderPath = `./tmp`;

  if( fs.existsSync(folderPath) ){
    fs.rm(folderPath, {recursive: true}, (error) => {
      if (error) {
        console.error('Error deleting tmp folder', error);
        res.status(500).send('Error deleting tmp folder');
      } else {
        console.log('tmp folder deleted successfully');
        res.status(200).send('tmp folder deleted successfully');
        // res.status(200).send('Original file deleted');
      }
    });
  }

The vercel server logs are showing this error

Error creating folder: [Error: ENOENT: no such file or directory, mkdir './tmp'] {
  errno: -2,
  code: 'ENOENT',
  syscall: 'mkdir',
  path: './tmp'
}
File uploaded
{
  fieldname: 'uploadedPDF',
  originalname: 'Coding-Week-Orientation.pdf',
  encoding: '7bit',
  mimetype: 'application/pdf'
}
Error: ENOENT: no such file or directory, open 'tmp/Coding-Week-Orientation.pdf'

Use /tmp, not ./tmp.
