POST routes are not translated properly

[executionByFork]

I have a Postman collection from before Postman required licenses to export them. I would like to translate this into an OpenAPI format for use with Burp but it seems this tool does not account for POST routes properly. None of the post data is reflected in the OpenAPI output. From what I understand, POST data should be in the response body for OpenAPI 3.0 spec?

Example

python3 /opt/Openapi-Schema-Builder/openapi-schema-builder.py -i test.json -o test.openAPI

test.json
