Error when using $ref for components/parameters

[cvgaviao]

I was generating maven java OpenAPI Server project properly while evolving my openapi model.
But when I moved some parameters to components/parameters and referenced them inside paths I started to get errors on the generation.
See the example below. It contains 2 parameters.

  /mycollection:
    get:
      operationId: listCollection
      parameters:
        - $ref: '#/components/parameters/some-ID'
        - name: orderBy
          required: false
          in: query
          schema:
            type: array
            items:
              type: string

When I let only orderBy parameter the generation is ok. But if I use the reference I got the error:
Exception during code generatione is undefined TypeError: e is undefined

I have used the online swagger-parser tool (https://apidevtools.org/swagger-parser/online/#) to test using the same api file. No error.
So the problem is not in the parsing ....
