.env errors in discord bot code

Hello! My code for the discord bot is:

import discord
import os
from dotenv import load_dotenv

load_dotenv()
Token = os.getenv('Token')
client = discord.Client()

@client.event
async def on_ready():
  print('We have logged in as {0.user}'.format(client))

@client.event
async def on_message(message):
  if message.author == client.user:
    return

  if message.content.startswith('//hello'):
    await message.channel.send('Hello!')

client.run(os.getenv('SDG'))

But i am getting a very, very long error message regarding an html file. I am not sure what to do. Please help me

I’ve edited your post for readability. When you enter a code block into a forum post, please precede it with a separate line of three backticks and follow it with a separate line of three backticks to make it easier to read.

You can also use the “preformatted text” tool in the editor (</>) to add backticks around text.

See this post to find the backtick on your keyboard.
Note: Backticks (`) are not single quotes (').
