设备向服务端提交reqeust时发生错误：Invalid response

问题描述

设备向服务端提交一个request请求时发生错误：Invalid response
服务端已经做出正常的反馈了
在提交另一个request请求时是正常的，这两个请求的后端返回数据格式是封装好的同一个类型，只是数据内容不一样。

复现步骤

1.错误请求示例：
设备端代码：

try:
    headers={
        'ai-token':'*******************************'
    }
    response = urequests.post(url="http://192.168.28.220:8080/aiApi/text2text?question=whoareyou",headers=headers)
    print("状态码:", response.status_code)
    print("状态码:", response.text)
    response.close()
except Exception as e:
    print("错误:", e)

设备端信息反馈：

错误: Invalid response

服务端代码：

    @PostMapping("text2text")
    public HnResult text2text(@RequestParam("question") String question) {
        log.info("文生文");
        String answer = text2TextService.talk(question);
        log.info(answer);
        return HnResult.ok().setData(answer);
    }
