#

the check name and why it fails, please help

DID I MAKE it clear?

astral egret Jan 16, 2023, 7:13 PM

#

What check?

jagged wolf Jan 16, 2023, 7:45 PM

#

Like @commands.has_role() or @commands.has_permission()

buoyant pike Jan 16, 2023, 7:51 PM

#

use an error handler

#

-d on_slash_command_error

glad waveBOT Jan 16, 2023, 7:51 PM

#

disnake.ext.commands.Bot.on\_slash\_command\_error


await on_slash_command_error(interaction, exception)```
This function is a [*coroutine*](https://docs.python.org/3/library/asyncio-task.html#coroutine).

The default slash command error handler provided by the bot.

By default this prints to [`sys.stderr`](https://docs.python.org/3/library/sys.html#sys.stderr "(in Python v3.11)") however it could be overridden to have a different implementation.

This only fires if you do not specify any listeners for slash command error.

Can you give another hint?

astral egret Jan 16, 2023, 8:10 PM

#

@bot.listen()
async def on_slash_command_error(inter, exception):

jagged wolf Jan 17, 2023, 4:26 PM

#

on the exception type

buoyant pike Jan 17, 2023, 6:19 PM

#

? depends on the exception

#

just read the docs, lol

jagged wolf Jan 17, 2023, 8:12 PM

#

buoyant pike ? depends on the exception

I said for when an @commands.has_permissions() fails

buoyant pike Jan 17, 2023, 8:18 PM

#

-d commands.has_permissions

glad waveBOT Jan 17, 2023, 8:18 PM

#

disnake.ext.commands.has\_permissions


@disnake.ext.commands.has_permissions(**perms)```
A [`check()`](https://docs.disnake.dev/page/ext/commands/api.html#disnake.ext.commands.check "disnake.ext.commands.check") that is added that checks if the member has all of the permissions necessary.

Note that this check operates on the current channel permissions, not the guild wide permissions.

The permissions passed in must be exactly like the properties shown under [`disnake.Permissions`](https://docs.disnake.dev/page/api.html#disnake.Permissions "disnake.Permissions").

This check raises a special exception, [`MissingPermissions`](https://docs.disnake.dev/page/ext/commands/api.html#disnake.ext.commands.MissingPermissions "disnake.ext.commands.MissingPermissions") that is inherited from [`CheckFailure`](https://docs.disnake.dev/page/ext/commands/api.html#disnake.ext.commands.CheckFailure "disnake.ext.commands.CheckFailure").

Changed in version 2.6: Considers if the author is timed out.
