Swagger-UI Maximum call stack size exceeded -> Backreference - swagger

Question

When calling my swagger.json from the swagger-ui I get an error:
Maximum call stack size exceeded
I guess it is because I have
Token which has an owner of Type User
User which has a Token of Type Token
When using the online-version of the swagger editior it can resolve the types. How can I configure swagger to resolve the types correctly?

Answer 1

I have the same problem and I removed format: date-time and the error is gone.
Still I don't know what causes the error. But without that format everything goes ok.

Answer 2

In FastAPI which uses Swagger UI, I was receiving the same error. I updated the FastAPI package to get the last version of Swagger UI and then set the value of 'syntaxHighlight' to False, like below:
app = FastAPI(swagger_ui_parameters={'syntaxHighlight': False})
Just search how you can set this param directly in Swagger UI. This may fix your issue.
