Sharp image uploader not working when running app with PM2 - express

Question

I have an express app that I am using Sharp to resize images after a user has uploaded them. When I start the app using 'npm start' I am able to upload the images with no issues, but if I use PM2 to manage the process the images don't get saved on the server. I can save them without using Sharp to resize them, it is only when I have the code for sharp that they don't get saved. Below is the code from my controller. Multer is processing the form and sharp is resizing the image.
doNewRecipe: function(req, res) {
for (var key in req.body) {
req.body[key] = req.body[key] || undefined;
}
var body = _.pick(req.body, 'title', 'description', 'ingredients', 'instructions', 'yield', 'prep_time', 'cook_time', 'categoryId');
body.userId = req.session.user.id;
if (req.file) {
var tempPath = req.file.path,
ext = path.extname(req.file.originalname).toLowerCase(),
//targetPath = path.resolve(finalUploadPath + req.file.filename + ext);
targetPath = path.resolve(finalUploadPath);
fs.renameSync(tempPath, tempPath + ext);
var newFileName = req.file.filename + ext;
var imageFile = tempPath + ext;
body.image = newFileName;
sharp(imageFile)
.resize(450, 450)
.max()
.toFile('./public/finalUpload/' + newFileName, function(err, info) {
body.image = newFileName;
fs.unlinkSync(path.resolve(tempPath + ext));
db.recipe.create(body).then(function(recipe) {
res.redirect('/recipe/view/' + recipe.id);
}, function(e) {
console.log(e.message);
res.render('error', {message: e.toString()});
});
});
//fs.renameSync(tempPath, targetPath);
} else {
db.recipe.create(body).then(function(recipe) {
res.redirect('/recipe/view/' + recipe.id);
}, function(e) {
console.log(e.message);
res.render('error', {message: e.toString()});
});
}
},

If you use path to determine where to save the file it will transport easily from one system to another. I actually created a few variables to determine where to save the file. Below is my code.
if (process.env.NODE_ENV === 'production') {
var finalUploadPath = 'hidden';
var googleTracking = true;
} else if (process.env.NODE_ENV === 'staging') {
var finalUploadPath = 'hidden';
var googleTracking = false;
} else {
var finalUploadPath = 'hidden';
var googleTracking = false;
}
sharp(imageFile)
.resize(450, 450)
.max()
.toFile(finalUploadPath + req.file.filename + '.jpg', function(err, info) {
body.image = req.file.filename + '.jpg';
fs.unlinkSync(path.resolve(tempPath + ext));
compressAndResize(path.resolve(__dirname, '../public/finalUpload/' + body.image));
db.recipe.create(body).then(function(recipe) {
req.flash('success', 'Recipe created');
res.redirect('/recipe/view/' + recipe.id + '/' + recipe.slug);
}, function(e) {
console.log(e.message);
req.flash('error', 'Error creating new recipe');
res.render('error', {message: e.toString(), csrfToken: req.csrfToken(), google: googleTracking});
});
});
