使用openapi typescript codegen,为什么这个Swagger模式生成Record<string,any>的模型?

我的swagger.json包括以下模式:

"schemas": {
            "BuildFruitBody": {
                "properties": {
                    "id": {
                        "type": "number",
                        "format": "double"
                    },
                    "name": {
                        "type": "string"
                    }
                },
                "type": "object",
                "additionalProperties": true
            }
        },

然而,当我通过生成axios客户端时 npx openapi-typescript-codegen -i ./swagger.json -o src/services/api -c axios ,得到的模型如下:

/* generated using openapi-typescript-codegen -- do no edit */
/* istanbul ignore file */
/* tslint:disable */
/* eslint-disable */

export type BuildFruitBody = Record<string, any>;

我是不是做错了什么?为什么模型不能反映模式?

下面是完整的swagger.json:
