scp command not working inside expect in bash script

while [ $FileLine -le $FileListLines ];
                do
                        # extract each line from FileList
                        str=$(tail -n+$FileLine ../$FileList | head -n1)
                        hostpath=$username@$ip:$str
                        export hostpath ip
                        expect -c '
                                spawn bash -c "scp -pr $env(hostpath) $env(ip)"
                                expect {
                                        "(yes/no)?"{
                                                send "yes\r"
                                                expect "*?assword:*"
                                                send "password\r"
                                                }
                                        "*?assword:*"{
                                                send "password\r"
                                                }
                                        }
                                '
                        FileLine=$(( $FileLine + 1 ))
                done

The above is a part of a bash script. The scp command in the expect block is not working, that is, files from the remote machine are not getting copied to the local machine.

The same scp command with the path and hostname is working fine when being run from the terminal.

Add expect eof at the end of the expect code otherwise the scp process would be killed right after the password is sent. (Also add a space between the pattern and { in the expect {} block though not sure if that's a problem.)

expect -c '
    spawn bash -c "scp -pr $env(hostpath) $env(ip)"
    expect {
        "(yes/no)?" {
            send "yes\r"
            expect "*?assword:*"
            send "password\r"
        }
        "*?assword:*" {
            send "password\r"
        }
    }
    expect eof
'

UPDATE

Just tried and "(yes/no)?"{ would not work. The space between the pattern and { is required so it should be "(yes/no)?" {.
