ERROR! Syntax Error while loading YAML

The error appears to have been in '/web.yml': line 13, column 3, but may

be elsewhere in the file depending on the exact syntax problem.

The offending line appears to be:

    - rolesForDoX

   - rolesForDoY

      ^ here

Solution: you will get such issue, if your roles not properly place with same space along with “–“.

Note correct formatted web.yml

web.yml

---

- hosts: localhost

  connection: local

  gather_facts: no

  roles:

    - rolesForDoX

   - rolesForDoY

   - rolesForDoZ

Correct formatted web.yml

web.yml

---

- hosts: localhost

  connection: local

  gather_facts: no

  roles:

   - rolesForDoX

   - rolesForDoY

   - rolesForDoZ

Run now you will get success:

ansible-playbook -i env/dev web.yml
