Error: ENOENT: no such file or directory

[NLanese]

I am aware that this error means "Cannot find file," howevever, I have this code copy and pasted, with an almost identical file scheme, and it works in one project and not the other. The code I have is as follows...

var req = request.post({encoding: null, url: 'https://pdftables.com/api?key=770oukvvx1wl&format=xlsx-single'}, function (err, resp, body) {
 if (!err && resp.statusCode == 200) {
   fs.writeFile("output.xlsx", body, function(err) {
     if (err) {
       console.log('error writing file');
     }
   });
 } else {
   console.log('error retrieving URL');
   console.log(err)
   console.log(resp.statusCode)
 };
});

var form = req.form();
form.append('file', fs.createReadStream('./TOM_Sample_ScoreCard.pdf'));

Given that this is being run from a file in the same directory as the pdf, TOM_Sample_ScoreCard.pdf I don't see why I am getting this error.

UPDATE: I moved both this file as well as the pdf further towards the outside of the directory tree, and it sent back the appropriate response... I am unsure how exactly the file organization effected this but hopefully this helps someone else
