Meteor-Up failures on 2 different servers - meteor

Question

I am experiencing failure every time I try to deploy to either an AWS/EC2 instance or a Digital Ocean droplet. With the EC2 instance I am using a pem file and with the droplet I am using password access. There were a lot of hoops to jump through to get through the mup setup, but that is finally successful on both instances. It's the mup deploy that fails on the Invoking deployment process: step.
Here's my mup.json for the droplet:
{
// Server authentication info
"servers": [
{
"host": "xx.xx.xx.xx",
"username": "root",
"password": "notmypassword"
// or pem file (ssh based authentication)
//"pem": "~/.ssh/id_rsa"
//"pem": "/users/alex/dropbox/awspems/projectmanager.pem"
}
],
// Install MongoDB in the server, does not destroy local MongoDB on future setup
"setupMongo": true,
// WARNING: Node.js is required! Only skip if you already have Node.js installed on server.
"setupNode": true,
// WARNING: If nodeVersion omitted will setup 0.10.33 by default. Do not use v, only version number.
"nodeVersion": "0.10.35",
// Install PhantomJS in the server
"setupPhantom": true,
// Application name (No spaces)
"appName": "projectmanager",
// Location of app (local directory)
"app": "/users/alex/dropbox/projectmanager",
// Configure environment
"env": {
"ROOT_URL": "http://xx.xx.xx.xx"
},
// Meteor Up checks if the app comes online just after the deployment
// before mup checks that, it will wait for no. of seconds configured below
"deployCheckWaitTime": 30
}
The following messages appear whether in the EC2 instance or the droplet instance:

The project works perfectly with no errors on my localhost.
Any ideas?
Thanks in advance, Alex Adams
And the solution is:
The mup logs showed that it didn't like a path designated for a folder to hold uploaded files. I changed the app to use GridFS, thus storing the files in the database. The app deploys correctly now.
