树莓派Pico W用urequests发PUT请求遇OSError: -2求助

我正在使用树莓派Pico W，设备已成功连接Wi-Fi，ifconfig()输出结果正常。采用的urequests代码来自micropython官方库，昨日测试时一切正常，但今日尝试更新记录时出现如下错误：

Traceback (most recent call last):
File "<stdin>", line 45, in <module>
File "request.py", line 10, in put_request
File "urequests.py", line 188, in put
File "urequests.py", line 76, in request
OSError: -2

已完成以下排查操作，但问题仍未解决：

• 通过Postman验证API服务器运行正常
• 将请求超时时间延长至10秒
• 重启设备

相关代码 #

request.py #

import urequests
import json
import MSAL

def put_request(id, json_data): 
    
    url = 'url/{}'.format(id)
    headers = {'Content-Type': 'application/json', 'Authorization': '{}'.format(MSAL.get_token())}

    response = urequests.put(url, data=json.dumps(json_data), headers=headers)
    print(response.text)
    response.close()

main.py #

def send_data():
    global data
    print('gonna send req here')
    while True:
        while data:
            d = data.pop(0)
            print('This one Going', list(d.keys())[0], list(d.values())[0])
            request.put_request(list(d.keys())[0], list(d.values())[0])
            print('Left over', data)
            utime.sleep(0.5)
        utime.sleep(1)
