Issue with Expect Script for SFTP.

Hi Experts,

I am learning expect and wrote the below script for automatic sftp into a server:

#!/usr/local/bin/expect -f -d
spawn sftp -v test@mumux503 # logs into mumux503 as test user
expect "password:"
sleep 20
send "test\r"; # sending the password for test user which is "test"
expect "sftp>"
send "get output.txt\r"
expect "sftp>"
send "exit\r"

However i am getting the password prompt. Any idea where the issue is. Also attaching the sftp -v test@mumux503 log below:
[!]root: ./expect.sh
spawn sftp -v test@mumux503
Connecting to mumux503...

Why dont you configure ssh keys for this ? I believe that would be much simpler and easier to do.
