Swagger Editor generated python-flask null type error

Question

I created my rest-ful api endpoint documentation on Swagger hub/Swagger editor. I have python-sanic based restful api endpoints. I'm generate and run python-flask server but I received error message.

Uncaught TypeError: Swagger 2.0 does not support null types ([object Object]).

I have investigated this problem but have not found a result for the solution.

Answer 1

The error message in the browser console:

Swagger 2.0 does not support null types

implies that you have type: null somewhere in your API definition. OpenAPI/Swagger 2.0 does not support nulls .

If you need nullable types, use OpenAPI 3.0 which supports nullable: true .
