How to convert dict or list to string in ansible

[Devops testing]

play: 

  - set_fact: 

         irules: "{{ rule | json_query('[*].definition') }}"

   - debug: msg: "{{ irules }}"  

output: 

"msg": [ "when HTTP_REQUEST {\n       switch -glob [HTTP::uri] {\n       \"*HAC*\" { pool char.hr.cal.ed.ABC.pool }\n         \n }        \n}" ] 

I'm expecting output to be in below format. 

Expected output:

 "when HTTP_REQUEST { 

        switch -glob [HTTP::uri] { 

        "*HAC*" { pool char.hr.cal.ed.ABC.pool } 

 }" 

I have tried parsing "from_json" to the above play and ended up with the error: 

"({{ rule | json_query('[*].definition') | from_json }}): the JSON object must be str, bytes or ``bytearray, not 'list'"}"

is there a way to convert list to string in ansibe? if not, any other suggestions would be appreciated to achieve "Expected output"`

As a json_query can have multiple results, the result of that filter is a list.

To get the first result you can use irules[0] or irules | first.

Hi Racke,

Thank you for your response. I have used pause module and it got printed as expected. Is there a way to store that printed content in variable? I have to copy that content to a file and add few extra lines to that file and have to apply that configuration content to firewall. Please let me now if you need any info 

play

 - pause:
             seconds: 1
             prompt: "{{ irules[0] }}"

output:

Pausing for 1 seconds
(ctrl+C then 'C' = continue early, ctrl+C then 'A' = abort)
[pause]

when HTTP_REQUEST {
    switch -glob [HTTP::uri] {

    "*HAC*" { pool char.hr.cal.ed.HAC.pool }

     }
}:
