Error when I start the server

[YoanGab]

I get this error when I start the server. The 1st request doesn't work. When I print the ctx, the channel is None for the 1st request but isn't for the next ones. Then I have this error when I use : await ctx.send(...)

Ignoring exception in on_socket_response

AttributeError: 'NoneType' object has no attribute 'id'

I tried with bot.command and it works

@bot.command(
    name="add_notif"
)

But not when I use slash.command

@slash.command(
    name="add_notif"
)

Can you give me full code?

[YoanGab]

I receive this error only on DMs, the 2nd message to send gives me the error but ctx["channel"] is None at the beginning of the function.

Okay, here's the problem: ctx.reply (as well as ctx.send (alias for reply), ctx.respond and ctx.create_response (alias for respond)) can never be called more than once, because these methods create a response for a given interaction. One interaction can only have one response. Instead of attempting to create multiple responses, you can use ctx.channel.send, which can be used an unlimited amount of times

[YoanGab]

I tried that but it doesn't even send 1 message, because ctx.channel is None. Moreover, ctx.send works when it's not the 1st time that someone interacts with the bot

[EQUENOS]

ctx.channel being None is super weird, maybe it's related to some caching reasons Speaking of ctx.send working more than once, it indeed should work like that, because it automatically detects whether to use create_response or channel.send, I forgot to mention that

[YoanGab]

What I don't understand is that it doesn't happen when I use @discord.commandinstead of @slash.command
