issue with line insert lininfile

[Tony Wong]

I keep getting errors when running an insert line task 

the task to insert is

- name: add line
  lineinfile:
    backup: no
    backrefs: yes
    state: present
    path: "{{ file_path }}"
    regexp: '^(\s*)[#]?{{ item.search }}(: )*'
    line: '\1{{ item.search }}\2\n\1{{ item.add }}'
  with_items:
    - { search: "{{ line.replace_with }}", add: "{{ line.line_to_add }}" }

------------------------------

but I keep getting this error
