"interactive password authentication" means "password typed by a human being in realtime authentication" and no substitutes for humans are acceptable to ssh. To arrange automatic logins, use ssh keys.

I using sshpass for authentication

No you are not. You are kludging passwords into scp with the expect brute-forcing tool. You wouldn't need it at all if you used ssh/scp/sftp as they were intended to be used -- it would work in a single line, unattended.

sshpass is also a terrible idea. Putting passwords on the commandline leaves them wide open to be viewed by snoopers.
