You're using a slash command, not a text command.
Text commands have the .message attribute in ctx.
Slash commands don't, because there wasn't a message for the slash command when you invoke it. You must use ctx.guild.id instead of ctx.message.guild.id.
You need to learn how to read the errors, it's pretty simple
It tells you which line has the error
why are you doing channel.strip()
channel is a TextChannel object, not a string
Think
What are you trying to obtain in that line
No like I'm asking a question
What do you want to get in that line
how are you not sure about code that you write
Now I'm completely not sure what your intentions are because you can't really answer what your code does 
but I presume you're trying to get the ID of the channel.
There's already an attribute for that, channel.id
You would've known that if you looked at the documentation of Pycord https://docs.pycord.dev/en/master/api.html#discord.TextChannel.id
that should be up to you?

If you know Python you will know what to do
You have absolutely no idea what you’re doing?
I can see that you’re trying to add a key (your guild ID) and a value for that (the channel ID) to the global chat data dictionary. In that case it should be replaced with the method I mentioned above on how you can get the ID of the channel.
Did you read this?
