[SOLVED] server.get_channel() returns 'NoneType' object has no attribute 'send'

I'm trying to make an embed with a button, and when you click on the button creates a channel and the bot DM you with a embed, but i got an error trying to get the channel by bot.get_channel(channel_id)

This is my code:

try:
    server = await bot.fetch_guild(server_id)
    channel = server.get_channel(channel_id)

    view = View()
except Exception as e:
    print(f"Error: {e}")
else:
    embed.set_author(name=server.name, icon_url=server.icon.url)

    await interaction.response.defer()
    await channel.send(embed=embed, view=view)

Also i try debug it using

print(channel)
print(channel.id)

Output:

None129
129xxxxxxxxxxxx6

OBS: I use interaction.response.defer() for the command, because it is log and have a delay to send.
