saving csv to parent directories not working Windows 10

[nwheatle]

I'm on windows 10, node v 10.15.3

I'm using csv-parser to read through a csv and alter the data row-by-row in an fs.createReadStream() call.
After the read, I try to use objects-to-csv to save the altered array of objects as new csv file. this works if I use a filename like './file.csv'. But, when I try to save in parent directories, the file is created but empty, and 'error caught' is thrown for every row of csv that is parsed.

What am I doing wrong? I have tried many path.parse/path.resolve/etc to troubleshoot but I still cannot figure it out.

const file = "C:/path/to/my/file.csv"
const csv = require('csv-parser')
const ObjectsToCsv = require('objects-to-csv')
absfilepath = path.resolve(file)

var csvarray = [];
fs.createReadStream(absfilepath)
.pipe(csv())
.on('data', function(data){
try {
csvarray.push(cleanData(data))
}
catch(err) {
console.log('error caught')
}
})
.on('end', function(data) {
// new ObjectsToCsv(csvarray).toDisk('./file.csv'); this works
new ObjectsToCsv(csvarray).toDisk('../dirname/subdirname/file.csv'); // throws error on 'data' file created but empty
})
})
