extract data with json_query from jinja2 variable in ansible

Question

I have a variable in the inventory that contains a JSON formatted data.

I want to extract a specific part of the data with json_query.

The variable contains a list of domains with related IP addresses (the JSON is valid):

DOMAIN={"domain1.net": {"addr": ["10.10.10.10", "10.10.10.20"]}, "domain2.net": {"addr": ["172.16.10.1", "172.16.20.1", "172.16.30.1"]}}

With an ansible-playbook, using json_query, I want to extact only the domain2.net IP addresses.

I've used https://api.gopipeline.io/jmespath-tester to validate the JMESPath query.

With this filter: "domain2.net".addr in the jmespath-tester, I got the following (expected) output:

[
  "172.16.10.1",
  "172.16.20.1",
  "172.16.30.1"
]

When I apply the same json_query with this ansible-playbook, I have no output:

Task

 ---                                                                                      
 - name: Extract addr for domain2.net              
   tags: test                                                                            
   debug: msg="{{ DOMAIN | to_json | from_json | json_query("domain2.net".addr) }}"

Output:

ok: [domain-lab-1] => {
    "msg": ""
}

I've tested also another query, by filtering only domain2.net in JMESPath online tester: https://api.gopipeline.io/jmespath-tester and I get this expected output:

{
  "addr": [
    "172.16.10.1",
    "172.16.20.1",
    "172.16.30.1"
  ]
}

But, when I try to do the same within an Ansible playbook, still no output: Task

 ---                                                                                      
 - name: Extract addr for domain2.net              
   tags: test                                                                            
   debug: msg="{{ DOMAIN | to_json | from_json | json_query("domain2.net") }}"

Output:

ok: [domain-lab-1] => {
    "msg": ""
}

If I try to print only the DOMAIN var, I can see the whole JSON output.
So, the variable is correctly read.

I'm using ansible 2.9.14.

I've read that the to json|from json from here:

Ansible : filter elements containing string with JMESPath

I'm not sure if is needed in my case, anyway adding or removing them does not make any difference.
