Automating SFTP with Expect

Automating SFTP with Expect
Hello all,
I've written an automated SFTP script to work with the Expect command. It recently occurred to me however, that if the client side box does not have the known host entry for the server, it will not work correctly. So I have added an expect for the known host prompt, and that part works correctly, however, it does not seem to continue past that point to enter the password successfully if the known host file has already been configured for that particular server. I'm assuming I need some sort of timeout for the expect of the known hosts warning, or an if of sorts. I'm not sure how to go about this with expect though. Any help would be great.
Below is my script:
#!/usr/bin/expect
set SYSTEM [lindex $argv 0]
set USER [lindex $argv 1]
set PASSWORD [lindex $argv 2]
set AUTOHOME "/etc/scripts/automation"
set TRIGDIR "/etc/scripts/automation/.engine_triggers"
set CTRIGDIR "/etc/scripts/automation/.client_triggers"
spawn /usr/bin/sftp $USER@$SYSTEM
expect "Are you sure you want to continue connecting (yes/no)?"
send "yes \r"
expect "password:"
send "$PASSWORD \r"
expect "sftp> "
send "put $CTRIGDIR/command $TRIGDIR \r"
expect "sftp> "
send "bye \r"
exit 0

Hi All,
Here is my Expect script, I don't get any error message when I run it. But the file never goes to other system? I also paste the output screen below.
When I run the script, the script runs so fast. But when I do it manually, it takes about 10 minutes for the file to transfer.
