I have a YAML file that has default value for two dict defined as follows:

sample:
  high:
    name: high-volume
    alias: hi-vl

hi-vl:
  ab1:    
    add:
      range: 0
      range1: 0
    remove:
      range: -1
      range1: -1

To iterate and get the values from jinja2 template i am using the code below:

{% for key, value in sample.iteritems() %}
{% set al = value.alias %}
{% for key1, value1 in al.iteritems()  %}

When I execute this template to generate the YAML file I get the error:

"msg": "AnsibleUndefinedVariable: 'unicode object' has no attribute 'iteritems'"}

The set variable is changing the variable as unicode.

If I substitute the direct value instead of value.alias in the set statement the iteration works fine.

I tried using filters like to_yaml, tojson but they convert to string and not render as dict.
