Проблемы с заголовком ответа сервера pico W ⇐ Python

[Anonymous]

Я пытался настроить небольшой сервер, на котором я мог бы в реальном времени определять значения всех контактов GPIO на pico pi. Сначала я нашел этот пример, который работал отлично, затем я добавил функцию в добавьте состояния контактов GPIO в html после некоторых вещей, которые у меня заработали, но я не сохранил их. И теперь не могу понять, как заставить его работать.
Строка, в которой я получаю: OSError -1

< р> conn.send(f'HTTP/1.0 200 OK\r\nContent-type: text/html\r\n\r\n')
Например, я также пробовал другие заголовки:
conn.send(f'HTTP/1.0 200 OK\r\nContent-type: text/html\r\nContent-Length: {len(response)}\r\n\r\n')
Но ни один из них, похоже, не работал
Весь код для справки:

# Import necessary modules
import network
import socket
import time
import random
from machine import Pin

# Create an LED object on pin 'LED'
led = Pin('LED')

# Wi-Fi credentials
ssid = 'SSID'
password = 'PASWORD'
def get_gpio_states():
gpio_html = ""
for pin_number in range(0, 28): # Adjust based on your setup
pin = Pin(pin_number, Pin.IN) # Set GPIO as input
state = pin.value() # Read GPIO state
gpio_html += f"{pin_number}{state}"
return gpio_html
# HTML template for the webpage

def webpage(random_value, state,gpio_states):
gpio_states =gpio_states
html = f"""
