I'm trying to get an image attachment through a Discord slash command interaction, so I can send a manipulated version back to the user, but I just can't seem to be able to do it.
The interaction itself comes through alright, but the "image" option's object is just {name: 'image', type: undefined, value: '972518871573602374'}. I think it's strange that the type is undefined despite me clearly using the .addAttachmentOption() method.
Here's my command builder:
new SlashCommandBuilder()
.setName("dither")
.setDescription("Apply a dithering effect to an image")
.addAttachmentOption((option)=> option
.setRequired(true)
.setName("image")
.setDescription("The image to dither"))
.addNumberOption((option)=> option
.setRequired(false)
.setName("intensity")
.setDescription(`% of dithering to apply (${intensityDefault}% by default)`))
.toJSON()
I thought the URL or something might be elsewhere in the interaction object but I couldn't find anything related to attachments. I also couldn't find anything about interaction attachments in the documentation so I thought I'd try here. Is it just an unimplemented feature? But why would there be a method for it then?
I'm also unsure of what the value property represents. I thought it could be the attachment ID, but even if I wanted to recreate the attachment URL myself I'd still need to know the filename.
According to https://discordjs.guide/interactions/slash-commands.html#parsing-options :
const attachment = interaction.options.getAttachment("image")
const name = attachment.name
const url = attachment.url
const proxyURL = attachment.proxyURL
Please note that, in the example above, I have used image because that was the name you attributed to the attachment -- .setName("image").
