I am trying to use $ref parameters in my openapi yaml, however as soon as I insert a $ref entry no code is generated (the folder is but it contains no files) and no error is thrown.

I took the code from #24, so my minimum working example is:

openapi.yaml

openapi: "3.0.0"
paths:
  /foo:
    parameters:
      - $ref: "#/components/parameters/MyParam"
components:
  parameters:
    MyParam:
      name: foo
      schema:
        type: string

But the same happens with my actual openapi definition. As soon as I add a $ref parameter, no code is generated.

command:

fastapi-codegen -i openapi.yaml -o app

I am using fastapi-code-generator version 0.3.5

Can someone help? Thanks!
