“等待仅在异步功能中有效” discord.js

Question

I'm writing this code and I'm getting a "await is only valid in async function" on the line with an arrow below. I've done a bit of searching around but I'm not entirely sure what's wrong.

       if (message.attachments.first()) {
        console.log("cool file.")
        if (verifyFile(message.attachments.first())) {
            console.log("epic file!!")
   --->     await request.get(message.attachments.first().url).then(async (data) => {
                fs.writeFileSync(`${directory}/${message.author.id}_unobfuscated.lua`, data)
                var options = {
                    'method': 'POST',
                    'url': 'https://obfuscator.aztupscripts.xyz/Obfuscate',
                    'headers': {
                        'Content-Type': 'application/x-www-form-urlencoded'
                    },

Answer 1

You need to make your function you are currently asynchronous. You can do it by using one of these options below. (depending on your function type)

Arrow function: async (parameters) => {}

Normal function: async function(parameters){}

Hope i could help!

Answer 2

To use await the statement which uses await needs to be directly in the body of an async function.

For example:

This works

const getValue = async () => 5

const myFunction = async () => {
   let val = await getValue()
   console.log(val)
}

This doesn't

const getValue = async () => 5

const myFunction = () => {
   let val = await getValue()
   console.log(val)
}

In your case:

let myFunc = async () => {
     ...othercode
    if (message.attachments.first()) {
        console.log("cool file.")
        if (verifyFile(message.attachments.first())) {
            console.log("epic file!!")
   --->     await request.get(message.attachments.first().url).then(async (data) => {
                fs.writeFileSync(`${directory}/${message.author.id}_unobfuscated.lua`, data)
                var options = {
                    'method': 'POST',
                    'url': 'https://obfuscator.aztupscripts.xyz/Obfuscate',
                    'headers': {
                        'Content-Type': 'application/x-www-form-urlencoded'
                    },
    ...othercode
}
