I had tried importing the openapi.json into an API tool, but was getting messages that the format was incorrect. Running against a validator, the following error was returned:
Error: Swagger schema validation failed.
Missing required property: version at #/info
After manually adding "version":"1.0.0", within the "info" section, I was able to import into my API tool but the validator showed a new error:
This API is valid, but it cannot be shown because it contains circular references
TypeError: Converting circular structure to JSON
--> starting at object with constructor 'Object'
| property 'properties' -> object with constructor 'Object'
| property 'children' -> object with constructor 'Object'
--- property 'items' closes the circle
