SFTP using Expect

Question

I have tried the script below to SFTP using bash script. But it does not work. Always error at password.

/usr/local/bin/expect <<EOF
spawn sftp PG1@dev1.dummy.com
expect "Password:"
send "abc123\r"
expect "sftp>"
send "cd /tmp\r"
send "get Data.dat\r"
send "get List.dat\r"
send "bye\r"
EOF

Here's the log file when I run the script above, after taking in all the suggestions from responders.
