attempt to index local 'args' (a nil value) error when the only optional argument is not provided

[error4OA]

whenever a slash command option is optional and not provided, it returns this error:

attempt to index local 'args' (a nil value)

this is my code:

local slashCommand = {}
local option = {}

slashCommand = tools.slashCommand("amount", "see amount of flops you/user have/has said")
option = tools.user("member", "the member")

option = option:setRequired(false)

slashCommand = slashCommand:addOption(option)

client:createGlobalApplicationCommand(slashCommand)

client:on("slashCommand", function(interaction, command, args)
    if command.name == "amount" then
        if db[ tostring( args.member.id ) ] then
            interaction:reply( args.member.name .. " has said flop " .. tostring( db[ tostring( args.member.id ) ] ) .. " times" )
        else
            interaction:reply( args.member.name .. " hasn't said flop" )
        end
    end
end)

any help?

github version

I didn't support global commands by default. Someone made a commit, but I can't tell if this is related.

Is "member" a required parameter?

no
