Swagger docs don't show example request body

[KnowYourselves]

Hello!

I have been having problems with the swagger documentation generated by this gem. Specifically the auto-generated swagger documentation doesn't show the body for the requests.

Version Information

• OS: Windows 11, WSL2 with Ubuntu20.04
• ruby: 2.7.4
• node: 12.22.7
• potassium: 6.4.0
• power-api: 1.0.0

Steps to reproduce

1. gem install potassium
2. potassium create test-power-api
3. App created with following options:
   
4. cd test-power-api
5. bundle exec rails g model Banana size:float weight:float
6. rake db:migrate
7. bundle exec rails g power_api:controller Banana
8. bundle exec rails rswag:specs:swaggerize
9. bundle exec rails s
10. Go to localhost:3000/api-docs

Expected result

The swagger documentation for POST /bananas should show an example body, for example, like the following documentation:

Actual result

The swagger documentation for POST /bananas doesn't show an example body:

Thanks!
