title: Unable to resolve Syntax errors in ansible playbook
body: <p>I have been trying to deploy my playbook but not sure what the error is . My playbook looks something like this :</p>
  
  <pre><code>- name: trying to find sb ami
     ec2_ami_find:
        owner: self
        name: SB
     register: ami_find
  
   - name : use custom ami
     ec2:
       image: "{{ ami_find.results[0].ami_id }}"
       instance_type: t2.small
       key_name: mykey
       region: us-east-1
       wait: yes
       register: ec2
  </code></pre>
  
  <p>I am getting error continuously this:</p>
  
  <pre><code>ERROR! Syntax Error while loading YAML.
  
  
  The error appears to have been in '/root/git-work/ansible/sparkbeyond.yml': line 16, column 3, but may
  be elsewhere in the file depending on the exact syntax problem.
  
  The offending line appears to be:
  
     register: ami_find
  
    ^ here
  There appears to be a tab character at the start of the line.
  
  YAML does not use tabs for formatting. Tabs should be replaced with spaces.
  
  For example:
      - name: update tooling
        vars:
          version: 1.2.3
  #    ^--- there is a tab there.
  
  Should be written as:
      - name: update tooling
        vars:
          version: 1.2.3
  # ^--- all spaces here.
  </code></pre>
  
  <p>Can some one please help me, why I am getting such error . I am using ansible version 2.3 on ubuntu machine </p>
