Cannot use `{data.length}` (Typescript)

i dont know the reason why {data.length} get error, it announced that 'data' is of type 'unknown'.ts(18046) Here is the code:

import fs from 'node:fs'
import path from 'node:path'

import { REST, Routes } from 'discord.js'
import { client } from '../src/index'
import * as dotenv from 'dotenv'

dotenv.config();

const rest = new REST().setToken(process.env.TOKEN!);
const commands = [];

const foldersPath = path.join(__dirname, '../commands');
const commandFolders = fs.readdirSync(foldersPath);

for (const folder of commandFolders) 
{
    const commandsPath = path.join(foldersPath, folder);
    const commandFiles = fs.readdirSync(commandsPath).filter(file => file.endsWith('.js'));

    for (const file of commandFiles)
    {
        const filePath = path.join(commandsPath, file);
        const command = require(filePath);

        if ('data' in command && 'execute' in command)
            commands.push(command.data.toJSON());
    }
}

(async () => 
{
    try 
    {
        console.log(`Started refreshing ${commands.length} application (/) commands.`);

        const data = await rest.put(
            Routes.applicationCommands(client.user!.id),
            { body: commands },
        );

        console.log(`Successfully reloaded ${data.length} application (/) commands.`);
        //                                   ^^^^
    } 
    catch (error) { console.error(error); }
}
)();

            commands.push(command.data.toJSON());
    }
}

(async () =>

    try 
    {
        console.log(`Started refreshing ${commands.length} application (/) commands.`);

        const data = await rest.put(
            Routes.applicationCommands(client.user!.id),
            { body: commands },
        );

        console.log(`Successfully reloaded ${data.length} application (/) commands.`);
        //                                   ^^^^
    } 
    catch (error) { console.error(error); }
}
)();

• What's your exact discord.js npm list discord.js and node node -v version? • Post the full error stack trace, not just the top part! • Show your code! • Explain what exactly your issue is. • Not a discord.js issue? Check out #useful-servers.

REST#put has a return type of Promise<unknown>, you can type it with https://discord-api-types.dev/api/discord-api-types-v10#RESTPutAPIApplicationCommandsResult alternatively i believe using the API class from @discordjs/core/http-only can be a good choice https://discord.js.org/docs/packages/core/0.6.0/API:Class

well i decide to do this if possible:

const data: any[] = await rest.put(
            Routes.applicationCommands(client.user!.id),
            { body: commands },
        );

const data: any[] = await rest.put(
            Routes.applicationCommands(client.user!.id),
            { body: commands },
        );

so i think ... it can search for the lenght, will it?

i would guess so, but you can also simply import RESTPutAPIApplicationCommandsResult from discord.js
