Why am I getting "unexpected end of file"?

I was following this tutorial on parsing arguments. When I run my script with or without arguments I get "line 45: syntax error: unexpected end of file". This is the line after the last line in the script. I simply don't see the error though (new to bash scripting...).

#!/bin/bash

#Explain arguments that can be passed in
argumentUsage(){
    cat << EOF
    usage: $0 options

    This script configures rsync to backup SOURCE to DESTINATION and provide notifications on status.

    OPTIONS:
       -h    Show this message
       -s    Source location
       -d    Destination location
    EOF
}

DESTINATION=
SOURCE=

while getopts "hs:d:" OPTION
do 
   case $OPTION in
    h)
       argumentUsage()
       exit1
       ;;
    s)
       SOURCE=$OPTARG
       ;;
    d)
       DESTINATION=$OPTARG
       ;;
    ?)
       argumentUsage()
       exit
       ;;
   esac
done

It's because you indented the EOF here

argumentUsage(){
     ...
     OPTIONS:
       -h    Show this message
       -s    Source location
       -d    Destination location
     EOF
}

Due to the indentation, bash doesn't "see" the terminating EOF, so effectively your here-doc is unterminated, which leads to “unexpected end of file”.
