How to adjust an awx workflow survey via ansible script

Get Help

I am trying to create an ansible template that will update a survey in a workflow regarding my msp’s meraki orgs and networkids. When I put in ansilbe code:

   - name: update survey choices
     awx.awx.workflow_job_template:
       controller_host: "{{ awx_host }}"
       controller_oauthtoken: "{{ awx_token }}"
       name: "MERAKI_NETWORK_CONFIG_WORKFLOW"
       survey_enabled: true
       survey_spec: "{{  lookup('template', 'meraki_update_survey.j2') }}"
       validate_certs: no
     register: uri_status

And this jinja

{ "name": "MERAKI_NETWORK_CONFIG_WORKFLOW",
  "description": "WORKFLOW AUDIT",
  "spec": [
{
  "type": "multiplechoice",
  "question_name": "Select the ORG and NETWORK",
  "question_description": "org network orgid",
  "variable": "org_network_select",
  "choices": {{push_meraki_list}},
  "required": true
        }
      ]
  }

The ansible job completes and I can use it in my workflow, however when I try to manually view the survey in awx, I get the following error message:

TypeError: Cannot read properties of undefined (reading 'split')
 
Is this supposed to happen when updating a workflow's survey from ansible rather than awx?
