discord-giveaways | 🎉 Complete framework to facilitate the creation of giveaways using discordjs | Chat library

I'm using the Discord Giveaways module.

I would like to know how to DM the host of the giveaway when their giveaway ended. I don't quite know how to do it yet.

This is what I know:

So because the the command first only worked when i put every option in 1 message ".sg #bot-test 1m 1 Test", that worked with args, but now i am trying to let the bot await the options from the user like you will see in the screenshot, but when it comes to the duration he gives me the error: UnhandledPromiseRejectionWarning: Error: val is not a non-empty string or a valid number. val={"channelID":"702608643329228821","deleted":false,"id":"710388381846077511","type":"DEFAULT","content":"2d","authorID":"391243477058584588","pinned":false,"tts":false,"nonce":"710388377081348096","system":false,"embeds":[],"attachments":[],"createdTimestamp":1589440188610,"editedTimestamp":null,"webhookID":null,"applicationID":null,"activity":null,"flags":0,"reference":null,"guildID":"672002616372363274","cleanContent":"2d"}

I would not know what i should change, https://www.npmjs.com/package/discord-giveaways, if you want to see how the package "works".

The part of my code:

So i am using the package "discord-giveaways" and i want to use the "exemptMembers" option which is a function and with which i can set who is not allowed to take part in a giveaway and i want that people who haven't joined a specific server cannot take part but i am not sure if coded that right and also there is the error: TypeError: Cannot read property 'members' of undefined that i don't really know to fix, so it would be nice if someone can say me what i did wrong.
