In OpenAPI specs where a property has the same name as the snake cased class name (in the example below, the snake casing is the lower case, but if it was, ex, InstagramId, then this would happen with a property named instagram_id) the code generated has a duplicated variable name (see image below).

The suggested fix is that the return variable name should have an underscore _, in this example, email_.

      "Email": {
        "type": "object",
        "properties": {
          "email": {
            "type": "string"
          },
          "verified": {
            "type": "boolean"
          }
        },
        "required": [
          "email",
          "type"
        ]
      },
