#Rejecting converter input

Hey, I want to create an argument in a slashcommand that takes a certain form. I've found out about converters, but I can't seem to find how to reject an input
(e.g. if you have a Member option, and you type something that's not a valid member, discord says "Not a valid user.". I'd like something like that)

What I currently tried:

class MoneyConverter(Converter[int]):
    async def convert(self, ctx, argument: str) -> int:
        amount = -1
        try:
            if(argument[-1] == "k"):
                amount = int(argument[:-1])
            elif(argument[-1] == "m"):
                amount = round(1000*float(argument[:-1]))
            else:
                amount = int(argument)
        except:
            raise BadArgument(argument)
        if round(amount,-2) != amount:
            raise BadArgument(argument)
        return amount

However, raising an exception doesn't give the result I wanted

this is error in command not in the class

#

just add this

#

async def balance(user:discord.Member):

@graceful relic

#

my thing isn't a member though, I want it to be a custom class / parser

graceful relic

Right now I have


@createorder.error
async def info_error(ctx, error):
    if isinstance(error, BadArgument):
        await ctx.respond(f'Invalid money amount entered: {error}')

but this only responds to the command when it's sent, rather than making sure the syntax is correct before it's sent like what's done with members, ints, etc

I currently have

async def setbalance(ctx,
                  amount: Option(MoneyConverter, description="Amount of money to set the balance to"),
... ):

However, when my money converter doesn't succeed in parsing the input, it currently sends an error after the message was sent. I want it to happen before it's sent (almost like a validator)

discord does not support bot-side validation of option values

#

most you can do is send a response with the error in text after the command is run
