Rollback in existing deployment fails

[George Tsoumplekas]

Hello all

I am using ansible  and helm operators in order to rollback a current deployment

The content of the path is simiral to the following 

{

   "spec": {

      "template": {

         "spec": {

            "containers": [

               {

                  "name": "patch-demo-ctr-2",

                  "image": "redis"

               }

            ]

         }

      }

   }

}

I have created in ansible the following command

- name: Demo

  k8s:

    api_version: apps/v1

    kind: Deployment

    state: present

    namespace: '{{ meta.namespace }}'

    name: my-operator

    definition: |

      spec:

       template:

         spec:

          containers:

            my-operator:

              image: {{ installed_software_image }}    

  register: output

when the command is running the rollback fails

NewReplicaSetAvailable\\\\\\",\\\\\\"message\\\\\\":\\\\\\"ReplicaSet \\\\\\\\\\\\\\"my-operator-66ff64c9f4\\\\\\\\\\\\\\" has successfully progressed.\\\\\\"}]}}\\": v1.Deployment.Spec: v1.DeploymentSpec.Template: v1.PodTemplateSpec.Spec: v1.PodSpec.Containers: []v1.Container: decode slice: expect [ or n, but found {, error found in #10 byte of ...|tainers\\":{\\"new-opera|..., bigger context ...|t\\":\\"2021-03-24T22:26:02Z\\"}},\\"spec\\":{\\"containers\\":{\\"my-operator\\":\\"image:\\\\\\"27.0.0.1:5050/my-ope|...","field":"patch"}]},"code":422}\n'", "reason": "Unprocessable Entity", "status": 422}

I put my question in stackoverflow

Is any one who can help to verify what goes wrong or to provide me a way to 

debug the command that I send

Thank you
