Issue in ansible playbook command?

As everyone has mentioned this does need you to use shell instead of command. Now you want to simplify this command so it can run first in bash. Which can be done easily using printf

$ printf "%s%s%s" '{"payload":{"header":{"channel_header":{"channel_id":"gll", "type":2}},"data":{"config_update":' $(<jaguar_update.json'}}}' | jq . > jaguar_update_in_envelope.json

$ cat jaguar_update_in_envelope.json
{
  "payload": {
    "header": {
      "channel_header": {
        "channel_id": "gll",
        "type": 2
      }
    },
    "data": {
      "config_update": {
        "name": "tarun"
      }
    }
  }
}

So now our commands runs without issues. Next is to move it with bash -l -c format. So instead using -c which requires us to pass the whole command as one parameter, we use the multiline commands

$ bash -l <<EOF
printf "%s%s%s" '{"payload":{"header":{"channel_header":{"channel_id":"gll", "type":2}},"data":{"config_update":' $(<jaguar_update.json) '}}}' | jq . > jaguar_update_in_envelope.json
EOF

But this fails with an error

{"payload":{"header":{"channel_header":{"channel_id":"gll", "type":2}},"data":{"config_update":{bash: line 2: name:: command not found
bash: line 3: syntax error near unexpected token `}'
bash: line 3: `} '}}}' | jq . > jaguar_update_in_envelope.json'

This is because the EOF format will treat each new line as a different command. So we need to replace all new line characters

bash -l <<EOF
printf "%s%s%s" '{"payload":{"header":{"channel_header":{"channel_id":"gll", "type":2}},"data":{"config_update":' $(sed -E 's|"|\\"|g' jaguar_update.json | tr -d '\n') '}}}' | jq . > jaguar_update_in_envelope.json
EOF

And now in ansible

- name: a play that runs entirely on the ansible host
  hosts: 127.0.0.1
  connection: local
  tasks:
     - name: Solve the problem
       shell: |
           bash -l <<EOF
                printf "%s%s%s" '{"payload":{"header":{"channel_header":{"channel_id":"gll", "type":2}},"data":{"config_update":' $(sed -E 's|"|\\"|g' jaguar_update.json | tr -d '\n') '}}}' | jq . > jaguar_update_in_envelope.json
           EOF

And the result

$ ansible-playbook test.yml
PLAY [a play that runs entirely on the ansible host] *********************************************************************************************************************************

TASK [Gathering Facts] ***************************************************************************************************************************************************************

$ cat jaguar_update_in_envelope.json

      }
    },
