STEPS TO REPRODUCE

Create build.yaml and manifest.yaml as per below files.
Download open api yaml from https://developers.nutanix.com/api/v1/namespaces/networking/versions/v4.0.b1/yaml and convert it using https://editor-next.swagger.io/ to json format.

build.yaml

---
- hosts: localhost
  gather_facts: yes
  roles:
    - ansible.content_builder.run

manifest.yaml

  path: /Users/pradeep.bhati/work/codebase/codegen/content_builder
  namespace: nutanix
  name: ncp

EXPECTED RESULTS

Code generation should go fine.

ACTUAL RESULTS

Failing with error as above.

[kksat]

I was able to overcome this issue by moving line

ansible.content_builder/roles/module_openapi_security/templates/doc_generator.py

Line 875 in 15a0742

post_properties = OrderedDict()

Above one line, so it looks like this

        post_properties = OrderedDict()
        if request_fields:
            post_properties.update(

[tlourey]

I'm having the same issue as OP.

@kksat fix let me continue but I then ran into an issue with module_openapi_security__' is undefined. Not sure if related or not.
