ubuntu digital-ocean systemd

I am creating the systemd service file on a DigitalOcean Server which has has ubuntu 18 and NGINX as a web server.

The script at systemd service file is:

[Unit]
Description=gunicorn daemon
After=network.target

[Service]
Type=oneshot
User=root
Group=www-data
WorkingDirectory=/var/www/computationalMarketing
ExecStart=/var/www/computationalMarketing/bin/activate
ExecStart=/var/www/computationalMarketing/computationalMarketing/code/computationalMarketing/gunicorn --access-logfile --bind unix:/tmp/gunicorn.sock computationalMarketing.wsgi:application

[Install]
WantedBy=multi-user.target

The error log is:

Warning: The unit file, source configuration file or drop-ins of gunicorn.service changed on disk. Run 'systemctl daemon-reload' to reload units.

root@tfm-rius:/var/www/computationalMarketing/computationalMarketing/code/computationalMarketing#

Is this error related with the user used at service body, or maybe with one of the execStart command?

Edit:

I changed the user at service body to: www-data

Now, the log error is: gunicorn.service: Failed to execute command: Permission denied

Which user should be used? How can I correct this error?

Edit2

As Oliver says in the comments I exec:

ls -la /var/www/computationalMarketing/bin/activate

The output is:

-rw-r--r-- 1 root root 2243 Jun 28 10:11 /var/www/computationalMarketing/bin/activate

I have two ExecStart due I have to activate the virtualenv first and then activate gunicorn to allow app to work.

Log after execute: chmod 755 /var/www/computationalMarketing/bin/activate
