Discord.js says "message is empty" but console.log shows data

Question

I'm currently working on a project that sends the information of my google-spreadsheets to a discord channel. So, I have some questions:

1) The final data (value), when I try to console.log(value) , it worked!

So that means it does get the data from google-spreadsheets and set it to (value).

But when I try to do msg.channel.send(value) , it responds to me with a crash and says can't send an empty message which makes me confused, why?

And therefore I can't send this value to my discord channel.

2) My final data (value) as shown at the bottom of my code, is actually an array like this:

{ values: [ [A] , [B] , [C] , [D] , ... ] }

And I don't know how to change them into A,B,C,D form. Does anyone know how to convert them?

const { google } = require('googleapis')
async function google_sheet_get() {
    const auth = new google.auth.GoogleAuth({
        keyFile: "./google_sheets/Google_credentials.json",
        scopes: "https://www.googleapis.com/auth/spreadsheets"
    })
    
    const client = await auth.getClient()
    const googleSheets = google.sheets({version: "v4", auth: client})
    const spreadsheetId = "My Sheet ID"
    const getRows = await googleSheets.spreadsheets.values.get({
        auth,
        spreadsheetId,
        majorDimension: "ROWS",
        range: "'Day1'!B1:F24"
    })
    return getRows.data
}

client.on('messageCreate', msg=> {
    if(msg.content.startsWith(settings.prefix+'ttes')||
    msg.content.startsWith(settings.prefix2+'ttes')) {
        sheet.get().then( value => msg.channel.send(value))
        msg.channel.send("Command ttes success.")
    }
})

Really appreciate the help, thank you.

Answer 1

I'm guessing that value is not a string, when you look at channel.send() , it accepts either string, "MessagePayload" object or "MessageOptions" object, so if the value is an object it tries to interpret it as either one of those and it fails because the required properties aren't there.

Try converting it to string before sending it, like: msg.channel.send(`${value}`) or msg.channel.send(value.toString() .

And as for the second part of the question you might want to take a look at Array.flat() .
