Ansible Install & Configure FTP Server on Linux Playbook

Question

I am trying to install and configure a FTP server using Ansible. I an running into syntax error. Can you please tell me correct syntax? I am not sure if it is a problem with looping through the list. The error message is not very helpful. It is saying that there is a problem with the first item in the list. Thanks.
